The S-AUJP v3 is an auto bin and because I will run with a manual TKO-600 I was wonder if I can just copy all the differences that show Tuner Pro and make just a paste at the AXCN.

Would be the hard code changes implemented at the AXCN?

I will not touch all the TCC related.

Any advice is welcome.

Not totally sure, but I think you can use an auto bin in a manual car, but not the other way around. I believe there is a version 4 in the works, or even out by now, that is for manual guys. Either way you will still have the fueling to 6400 RPM, and the PW cap fix.

I just removed all the TCC and auto stuff and run S-aujp in my vette

TP won't define all the cal differences if your using a public xdf.
There are basically 3 sections of hard code that are different for an MT car.-That I could find among the 1000's of differences a comparison I did.
I could have missed one but it was very tedious. I need to go back and try it again with a new editor I aquired.
All were IAC related and 2 of the 3 I'm pretty sure are only used during an ecm hardware failure. I couldn't figure out what scenario GM had in mind for the 3rd one. And not all SD MT bins have all 3 sections either???? I added all 3 to S_AUJPV4 and the one beta tester that had an AT didn't report any new idle problems. The AUJP idle limiter was simply adjusted up out of the way. And I used the AXCN cal as the basis for the MT beta tester.
Not need to mess with the AT cal section. It isn't used when the MT code is used. The code simply looks at the trans select bit then goes to the appropriate section of code to run.
But AUJP's cal section is nowhere near correct to use with an MT.

Hi guys,

brutalform
I am shore that you can drive in a M/T car with a A/T car I did that with my old $6 setup. But it was not ideal to tune.

-=Jeff=-
Does your post mean that your car runs as you expected right from the start?

Z69
I have read your post several times to assimilate it.
I use a public xdf the "8d_v03.xdf"
When you use the TP to see the differences you can switch the option "Limit search to defined items only" if I let unmark the option I get lots of differences and here is where I think, where should I start? Use the AXCN and apply all the changes or start with the S_AUJP and see it the engine is happy.

I read that if the trans select bit is selected to M/T the code ignore the A/T. That will simplify a lot.

I have found also that there are some differences at the next items:
Are those also typical for a M/T ?? it looks like the GM want to ignore them.
Highway Mode Fuel Min. Temp. (AXCN set to 151°C)
Highway Mode Fuel Max. Time (AXCN set to 0 Sec.)
Highway Mode Fuel Min. Vehicle Speed (AXCN set to 255 Mph)

Allow me to explain my setup.

I am close to the first firing of my 350 engine, need to install the new wiring.

I will use 16 injectors!!!!!!!!! yes! 8 would be the 24 lbs for the petrol section and the other 8 would be for the LPG injection.

The LPG injection has his own ECM that copies the petrol injector pulse and use the corresponding pulse for the LPG injectors.

I need to find a base setup for both systems so that in case of failure both will run and not let me down at the side of the road.
Limp Home of petrol should allow to run the LPG too.
I know that is a challenge but it should work, I am shore of it.

I use the Prominator and soon will be loaded with some test bin's but I want to have a hard E-PROM as the back-up option.

Here is a detail picture of the injectors at the HSR manifold.

Thanks for the comments and please be invited to give more help.

yeah it ran like it did with the AXCN PROM that was in there before

3.8TransAM

About 95% of the difference in stick to idle prom's is IAC settings.

Obviously needed differently due to loading variances between the two.

Also have some timing changes due to areas u could see with a stick vs a converter.

Least its what I have found.

I have made either work, just takes some time and playing and what you consider good enough.

Nice to know Jeremy.
I know that I need to do a full tune but it is the brake-in period what I am concerned, but using the Prominator I will be able to switch the bin' in case that don't want to go.

My engine setup is as follow:
New short block 350
HSR with 24 lbs injectors
AFR 180 Eleiminator series.
58 cc combustion chambers. 0.04" of quench.
Static 10.2 CR and 8.26 CR dynamic.
SKY CAM # ISKY 257_265-HYD @0,050" 209°/217°
Scorpion rockers ratio 1.6 this give a lift of IN 0.496 EX 0.517
Differential ratio 3.31

So as you can see I need to do a lot of tune to get it right and I hope that the S_AUJP will give me the change to get above the 400 HP @ the crank.

I understand that a A/T with the converter has more to do at idle, but is that the only reason why all the A/T runs at a lower RPM than the M/T?

I was going to jump in here too, but then I see you've already been chatting with the experts, so I won't cloud the issue...

Wow!
Neat setup for sure. You could always change the LP over to NoS
Do you have the "test version" of V4 yet?
I just added another feature, The VSS/TPS retard for some traction control.
Was reading an old RBob thread and couldn't help myself.
I think Vern needs it too!
Should be the last mod before it gets out. Vern has had good results with the latest (before my adder) while using the MT option.

Hi JP,

How is the life treating you these days?

Thanks for the comments.
As you know we are bushy for a long time and it looks like we are close to the finish line.
NOS for me? I can't manage a normal car!

I use to go at the track and those NOS guys have nothing to say there! It is the fun at the corners what make the differences.

Anyway I don't know where I can download the V4 I will test in extend, because if I have understand Z69 and you did a lot of work for the M/T at this revision.

Traction control? what is that is a Cobra?, Please don't give me bad ideas because others the Cobra would be never finished.
I like the torque over-steer "right leg control" is something for v8 revision?

I wonder why the M/T AXCN bin has these values at:

Highway Mode Fuel Min. Temp. (AXCN set to 151°C) (S_AUJP v3 = 59.75°)
Highway Mode Fuel Max. Time (AXCN set to 0 Sec.) (S_AUJP v3 = 60 sec.)
Highway Mode Fuel Min. Vehicle Speed (AXCN set to 255 Mph) (S_AUJP v3 = 53 Mph)
It looks like there is a deviation at the M/T bin's way of using the Highway Mode!

Any thoughts?

Just found the information at this thread:

Highway mode is disabled in stock bins AFAIK. So the settings may or may not work. V3 came with Hwy mode enable and is the first thing most people should disable until they are ready to test it's function on their setup. IMOP....
Have a look at the difference between the SA, PE, AE settings.
The public xdf's don't define the entire cal section. Which leads to a lot of posts saying there are only x differences between f & y body bins.
Which usually simplifies what is actually true. Will both work? Yes.

On a stock AT car. You will have problems with a higher MT idle setting.
Raise the idle on one of your AT cars using just the gas pedal and take it out of park. Make sure you have enough room for this test.

Feature creep and 7 day work weeks have caused lots of delays in the V4 project.

Cobra289

Hi Z69,

Thanks!
I will have a close look to the SA, PE, AE and the IAC settings.

The test that you propose to do with a AT car is not possible, we just only have a little Opel Astra with MT.
But I can imagine that the car will have a great jump!

Once I have done all the mechanical and wiring installation I will get some time and probably I will dig more in the xdf's world.
I did once a couple changes at the ECU time and I think that extend the xdf's would be an interesting item to work on it.

7 day work! Wow! that is a lot man. Here in Europe (Holland) we pay a lot taxes (60%) but we work only????? 5 days. I think that JP can tell you about this crazy world! he has visited several times our little country.

Never mind! I follow the other thread "First tune after major engine build" because it is a comparable situation as what I have here and probably I can learn something there.

Thanks for your input!

I'm done with creeping on this version. Time to put it to work.

JP: Thanks for putting in the work, this sounds like exactly what I'm going to need.

305 with AL 'vette heads and a 220/230 114LSA cam. The plan is open loop all the time, it's going in a road race car. Shifting it at 6500 and if it idles at 1500, I don't care
