Right now i'm converting a 91 Z28 with the 350 over to a six speed. Am wondering would it be better to start with the AXXD.bin (92 305/5 speed G92) or the Vette ARFP.bin (I'm assuming it is from either a 90 or 91 vette).

On the one car that we did a few months ago we just used the AXXC.bin with the AUJP.bin tables copied over into it. It works great but I forgot about the Vette bin and the G92 bin.

Why not try both?.
Experimenting can lead to interesting results.

As much as I would love to, it isn't my car Or else I would. I only have the car till friday and the owner lives 4 hours away.. It would be kinda neat to see what the timing tables of the vette bin would work with the iron head's.

I think I'll just go on the safe side with the AXXD.bin with the AUJP.bin fuel, timing, etc. tables.

Hi Kat, I have a 350 L98 with the 5 spd and have been having a whole lotta fun trying to figure out what is best to use also, I think I ended up using the ARAP bin and just changing the main variables. If you would'nt mind would you send me the bin you end up using, as I would be very interested in seeing what you end up with.

I'm still having tons of issues with idle surge, rough ride at low RPM, and engine running lean.

if you want to send me an email StevenK@austin.rr.com i would apriciate getting a look at someone elses work. (this applies to anyone that has tried to make a manual tranny L98 bin too)

I take it that you are still using the '165 ECM? The ones that I'm talking about are for the '730 ECM and wont work for ya.

If ya want, look for a copy of the AYPY.bin It is Vette 6 speed bin for 89.

I just got done with this swap in the past 10 days...

I used AXXD. I brought in my old VE and timing tables, my injector and cylinder volume values, left most of the AXXD IAC / AE stuff (i figure that a manual probalby operates way differently than an auto in terms of AE etc.), basically i went table by table and made a guess about which would make more sense to use from my old AUJP (which i had tuned quite a bit on) vs. use AXXD.

I also changed the road speed constant (t56 with the 17 reluctor thingy VSS) following info posted on here. I also did the instrument cluster bit hack to get my speedo in the ballpark. These both worked quite nicely (well, after I hacked the right bits..)

I ended up burning about 4 chips (i wasn't setting the right bits for the speedo divisor) but other than that everything has worked well, i've had NO drivability problems. I haven't thrown diacom on it yet, i'm sure i'll run into a few oddities here and there but you can get quite close just by importing the right tables into AXXD. If you use the vette prom, you have to disable the oil temperature code (if memory serves), and beyond that - i don't know.

one of my projects is to find an output on the '730 so that I can control the reverse lockout solenoid on the t56. the codework should be easy (similiar to the hack that (sorry i forgot who you are!) did to include WBO2 data in the ALDL data stream (just hook the code and insert some of your own), but have to find a way to control an output. maybe the fan2 output that vettes use? not sure yet, have to review a schematic, i think they may not be available now with the loss of diy-efi, but not sure. i haven't looked into it yet.

anyways, axxd will work. i don't know what advantages the vette prom would hold...but i'm a simple person, if axxd works i'm sticking with it.

I ended up using the AXXC then copying everything over from a AUJP.bin worked well actually..

BTW I was thinking about try to use the TCC output to control the reverse lock out solenoid. I don't see why it wouldn't work.

Why didn't I think of that? It makes perfect sense, the wiring is already down there. It probably woudln't take much to hack a few lines of code to make it happen.

in fact...there is already code in AUJP to lock the TCC above (I think) 75mph regardless of any other conditions. Could probably change that value to say, 3mph, wire the output to a relay, let the relay operate the reverse lockout and voila.

When I get around to trying it I'll post my results.

There ya go. If one of my cars had a 6 speed in it I would of tried it buy now. lol

Good luck with it man.

And here ya go if you are looking for the ouput off the ECM for the TCC
