Another Turbo 2.8 in progress

Re: Another Turbo 2.8 in progress
Noisy alternator. Its not a bandaid, its a solution. The alternator has less than 1000 miles on it so its pretty much brand new and replacing it is out of the question.
Noise in the 12v line is causing resets, a quality noise suppressor does exactly what the name suggests, which will solve the problem that I am currently having.
I have done some extensive reading on the msextra forums and have concluded that the ms1 processor along with the v3.0 board, when put together are more susceptible to noise than say an ms2 on the 3.0 board, etc...
Everyone who has swapped the ms1 cpu with a ms2 cpu, resets and noise are gone, so my conclusion is that the MS1 processor is HIGHLY sensitive to noise, and i am not quite ready to swap an ms2 cpu yet.
The noise existed with the stock computer and I have never had problems with noise, aside from the whine in the speakers coming from the alternator. Noise is a fact of life for some of these cars, mine has had that whine since I bought it. Replaced the battery and alternator and it didnt go away. Tried just about everything BUT a noise supressor.
Simple fact of the matter is, I bought the suppressor thats sold to do what it does, which so happens to be what I need it for; to call it a bandaid is nonsense, its a fix when all else has been ruled out.
Kinda like saying sunglasses are a bandaid. Whats the fix, stay out of the sun? Get my point? I understand what you are saying but electrical noise is a fact of life, and in some cases no matter what you do, you cant get rid of it.

No, a noise suppressor IS a band aid, you're not addressing the problem, you're putting a band aid on it, plain and simple. I say this as someone who has worked on automotive electrical for well over 20 years. I have NEVER come a cross a car where I have not been able to fix any sort of electrical noise issue, the correct way and not with band aids.
I have installed audio systems for as long and have been able to solve noise in every case, sometimes the repair was to replace defective or damaged product. So the noise you hear, an "audible tachometer" as the industry refers to it as, is indicative of poor grounding, possibly poorly routed wiring, poor condition battery (battery acts like a filter) and/or defective components.
If you don't repair the problem at the source, it's only a matter of time before it gets worse and your "noise suppressors" become in-effective.
The MS issues seems to indicate that the power supply of the MS in-adequate, and should be improved to filter more of the noise out. IIRC the MSII daughter board has an additional power supply section, that would be responsible for additional filtering.
Noise is not a fact of life for any car, that is fact.

Valid but moot in my application, its not noise causing resets.
I have gone over every single ground with a fine tooth comb, earlier in the thread I also tried power directly from the battery with no change. Moved the ms grounds from the chassis to the head, separated and isolated the sensor return wire, moved spark plug wires away from everything, new dizzy, wires, coil, plug, etc...
One thing i noticed, when it drops out, the afr goes lean. Never noticed it before because with the bad dizzy when it dropped it went rich. So its a no fuel condition i believe.
I havent tried to drive it with the bypass unplugged but i bet it runs perfect again. Ill update tomorrow.
So far I have 99% of what i need for the turbo install, pics coming tomorrow

Re: Another Turbo 2.8 in progress
sorry for the delay but heres my .msq and a datalog. I realize that the datalog isnt very long, and its mostly in warmup, but it did hiccup once. Then megatune completely locked up and crashed my laptop, so thats why its so short.

Re: Another Turbo 2.8 in progress
I have seen a couple threads on the msextra forums where over boost was causing problems. Being Im still NA, wouldnt I set it to 100kpa instead of -14.7?

Re: Another Turbo 2.8 in progress
Lets see if I have this right.
Bypass unplugged, no timing changes, means the rotor phasing is fixed, no miss or resets.
Plug in the bypass, rotor phasing changes with timing, misfires and resets.
If this is correct, then wouldnt it mean the timing controlled by the MS is causing the miss, perhaps firing the wrong cylinder due to the changed rotor phasing?
Is that correct?

Re: Another Turbo 2.8 in progress
sorry man ive been busy didnt even relized u had been posting , ill look over the tune here tonight when i get out of work and get back to ya
to be sure of rotor phasing pull the cap off and see how the rotor is locatated in relation to the number 1 terminal with the engine set to tdc on #1

I think everything is working as it should, because it runs great. But that miss always happens around the same conditions, which as far as I can tell is around 25% throttle, low load. Wont do it with no load, and only if the bypass is plugged in.
If the bypass is unplugged(base timing *10 btdc), it doesnt do it at all. Its gotta be the Megasquirt. Everything else has pretty much been eliminated.
Something to do with the MS controlling timing or some specific setting is amiss. Im at a loss to think its anything else, we have done just about everything.

Re: Another Turbo 2.8 in progress
You can check for limp mode advance via the timing light. Same as setting the base timing but increase the engine RPM. At some point the timing will suddenly advance.
The RPM at which the timing increases varies from vehicle to vehicle, but it is usually in the 1600 - 2000 RPM range.

Anyone think theres a chance that the original faulty icm causing real misfires may have screwed something up on the MS board before it was replaced? I dont think it did and had a look at the board and it was fine. Plus the fact that it runs fine other than that slight miss, which is nothing like the miss I was having with the faulty icm.
The overboost setting has caused resets and misses for other people, but im kinda unsure about that, even though it makes sense. I mean, wouldnt it be set to 100kpa for na instead of -14.7? When it misses im usually cruising trying to maintain speed, which with the throttle blade mostly closed, would result in a higher vacuum right? But if thats the case, then wouldnt it do it idling in gear too? Or is it only limited to happening under load?
Just throwing some thoughts out there cause im about ready to figure this crap out and be done with it. At this rate I'll never get the turbo on.

I can confirm its not the overboost setting, i set it to 23psi and still does it.

Re: Another Turbo 2.8 in progress
you think maybe changing the injector squirts may make a difference? I have one ground connection that I am about to go out and check, the ground I moved when I moved the battery to the other side of the engine bay.
Also, dont know If I had mentioned this before, but both banks of injectors are getting power from only one injector fuse, the other injector fuse is what I'm using for the MS power.
LOL, on one efi site, they say to put the sensor return with the rest of the MS grounds(how I had it wired originally), on another it says to seperate the return from the ECU grounds(which is how mine are now).

squirts should be 2 squirts alternating
u should prolly seperate the injector power on my car power fro all 6/8 injectors comes form a 40 amp relay
i cant get tuner studio to run on this computer friggen hate windows 7
edit i finally got it to install

Re: Another Turbo 2.8 in progress
Man these new relays are getting cheesier and cheesier. The original fan relay lasted 22 years, the replacement lasted 2 years, and the one I just swapped out looks like the crappiest case I have ever seen, its almost transparent. If it goes anything like the last one I may get a year out of it, good thing its lifetime replacement.

Re: Another Turbo 2.8 in progress
Can I put the balancer timing mark to the *10 btdc mark for tdc on 1? or *0 btdc? is there an easy way to do that or do I have to take the plug out of #1 and find the compression TDC on 1 with a screwdriver?

Re: Another Turbo 2.8 in progress
take number one plug out and put ur finger over the spark plug hole while u turn the engine over u will feel it build compression, and then u will know when u are getting near tdc
set the timing mark to 0* that is tdc
actually set it to 10* btdc so i can see how the reluctor wheel lines up at ur base timing

Sounds good. Ill go out and get those pics now. I might just use my old cap and just cut out the whole center cause its no good anyway. Ill just leave all the outer towers intact.

Dont mind the mess, its like that cause i just pulled the old cap off with the wires still on, that looped wire is the ground from the shielding to the dizzy screw.

Re: Another Turbo 2.8 in progress
u know what just put that cut cap back on , set the engine to 10* btdc and then line up the rotor with #1 , then tighten the dizzy , start the car and see what base timing is at.
we can change the offset/base timing in megatune to make it correct

Re: Another Turbo 2.8 in progress
ahh ok so the first to are at 10* btdc then never min my previous post
ugh i gota think about the rpotor phasing for a few mins
the reluctor is just past its peak at 10*
iirc rotor phasing is right but like i said i need to think about it for a few mins
on mine at 10* everything is dead on not just past like yours is
looking at it again that is a huge gap between the rotor tip and the terminal though . is the cap seated all the way?
adit again
lift the dizzt till u can spin the rotor and move the rotor back one tooth and drop dizzy back in and retime it i wanna see what it does

Re: Another Turbo 2.8 in progress
is it supposed to be perfectly aligned at 10 or 0? the rotor that is

Re: Another Turbo 2.8 in progress
it runs perfect other than that slight miss and the resets. Only under cruising, more or less throttle and it doesnt do it at all. they never occur at the same time, plus it doesnt happen with the bypass unplugged.
Im somewhat hesitant to move the dizzy, its dead on AFAIK. The only thing bothering me is the reluctor not completely lining up at 10*

Re: Another Turbo 2.8 in progress
Also the base timing may or may not be closer to either 9 or 11*, that might just account for the reluctor being slightly off.
Can I put the balancer mark at 10*, then loosen the dizzy and turn it till the reluctor lines up properly?

This is after moving the dizzy to make the reluctor line up. Balancer mark centered on 10°. I noticed that the dizzy shaft has a tiny bit of up and down play, but not enough that it would have lined up the reluctor. that little bit of play may line up the rotor though

Re: Another Turbo 2.8 in progress
Looking at the reluctor, it almost seems like its not seated properly on the dizzy shaft. Possible I got a bad dizzy? Then again that doesnt make sense cause it did it before on the old dizzy too..

Re: Another Turbo 2.8 in progress
that rotor looks like pos , how much of a gap between the end of the rotor and the terminal is there?
now what i want you to do is moove the timing marks so the the engine is at 35* btdc and take a picture of the cap/rotor again

Re: Another Turbo 2.8 in progress
It still missed, but it didnt reset at all and had extreme lack of power.
I guess cardone isnt as good as they used to be, thats the rotor that came with the dizzy.

Re: Another Turbo 2.8 in progress
About a playing card or 2. That little bit I turned the dizzy moved the timing from 10 to 0. The most confusing part? NO RESETS. What the hell???????

whats happening is before the rotor tip was to far away from the terminal the spark had to jump a massive air gap before getting to the spark plug gap causing a missfire

Re: Another Turbo 2.8 in progress
leave the distributor were its set then and go into the tunr and change the base angle from 10 to 0 and try again

Ill take another log and blip the throttle right after it misses.

Re: Another Turbo 2.8 in progress
Now if I can just get megatune to stop locking up. Started a datalog, recorded for a minute, then locked up. Pulled over and tried to restart megatune and it wouldnt work at all.
AFAIK(cause I cant tell unless megatune is connected) No resets and the misfire is gone.
Can I run the car at 0* as long as the MS compensates and leave it there?

all that was wrong was the rotor phasing setting base timing to 0* fixed it for the most part , it might still not be perfect but its close enough for now
the missfire or the arc inside the cap was causing the noise and resets
normally on a conversion like urs u do not need to check rotor phasing since its usually right with the stock ecm to begin with , but one out of 25 may have the issue u had

Re: Another Turbo 2.8 in progress
yes u can leave the base timing there since u reset the base timing to 0 in megatune the megasquirts compensates for it

Glad to be done with that for now. Now I gotta tune it I guess, wonder how long itll take me to finish that. Im about to say F the NA tune and just move on to the turbo install cause this wasted way more time than I expected.

Re: Another Turbo 2.8 in progress
I was starting to lose my mind trying to figure it out. So I am assuming that the dizzy was off from the factory then?

the boosted sections of the map should prolly get u 10.5 afrs to start so it should be safe to jump right in and tune the whole thing as u go
btw even if u tune n/a now the tune will be off once the turbo goes on , cause backpresure and ex flow changes, on a speed density system this has a big impact on fueling
