Heck I was getting that untuned.

97's are the only ones I have seen that have "one" o2 sensor also. Does the Sd and Alpha-n only have one o2?

They are the only ones I have heard of only having 1, but some 97's have 2 o2 sensor's as well.

Btw just an update... Tom is working on some timing histograms... last night I played with a tune a little bit (was busy) and got DFCO perfected. I played with the IPW vs VAC a bit more (brought it down) and afr's went up to 11.1:1...

Sounds good. I would like to see the histogram Tom made for you.

now i know nothing about writing code or programming, but these pcms are the same. if we wanted we could flash a 98 or 99 calibration onto a 97 comp. either way you could start out with no ipw table, flash a diff calibration and now have it. what im trying to get it is, is there anyway to manipulate the code, or add the code of the ipw table to say the 97 sd tune? its not the pcms incapability to have the ipw table on the sd one, its just the code for it isnt there. so i ask can it be added without doing a write entire, or what im really saying is can it be added without using hpt but say someone go in and program it in?

This would be something for HPT people to handle, and I do not think we will get that. It might not be possible either.

I've got a 98 z24 auto and it has no IPW vs VAC table... from the other vcm files i've looked at (with HPT) the IPW vs VAC tables are right under the injector constant, right?? Does this mean trying to fake a 2-bar is useless when I turbo since I can't change the fueling in boost since my car is alpha-n? I'm just upgrading to 440cc injectors and was planning on using HPT to do all the tuning (and yes I have a wideband

Something does not seem right. I have yet to see a 98+ file without it. People have done fake 2 bar map tunes without using the IPW vs VAC, but using it, or having it should make it sooo much easier and nicer. You can set-up 440cc injectors without using the IPW vs VAC.

my original ques was for more of along the lines without hpt. im going to blunt out say i KNOW that it can be done. obviously if you can do a write entire or just even because the pcms are the same hardware and same part number just a diff flash it can be done. originally one 97 will have no ipw but do a write entire to a 98 with it and now BAM!! you have an ipw table, that tells me it can be done.

here is some links to pics of a 98 without the ipw, but compared to a 99 with it.

notice main file(98) has 110 parameters whereas the compare(99) has 112
both are the same pcm are they not? so i ask what can be done to add those 2 parameters, with or without using hpt.

pretty much in my theory what needs to be done for that ipw table to be slapped into the 97 sd tune? we could use some comp programmer guys on this.

how do i get to the inner workings of the bin file ill try it


and none of that was an argument back toward you john, i totally agree with how it should be a thing handled by hpt guys, but i also agree we prob wont get that from them. so i wanna know if there could be anyone on here or with some knowhow to manipulate that sort of thing. i know there are some guys running around that have created their own ms code.


also i have multiple 97 and 98's without the ipw table.
one for example

Sure can.... In my SC LD9 on long highway I get 42mph.. City driving(work and around town) I get 27-30, depends how hard I drive it...

the best Hwy MPG i got with my blue car was 36.

BUT THAT WAS ON THE "@!#$Y" STOCK TUNE


Also, GM tunes cars to be SAFE and not blow up, if anyone is better, maybe ya should put a application in, Or sell your tune's.

Why would anybody want to work for a company that is slowly dieing.. My tunes are safe and I do "sell them", just not by mail order... Alot of it also depends on driving habits too..

Well, another update amongst all these off-topic posts....

Cold starts are fixed now... the only thing the car doesn't like is having the throttle blipped in the first minute or two of driving.... which I can live with. Once the car is fully warmed up it drives completely fine... stock-feeling off of boost and lots of fuel in-boost.

This weekend I will try to tune the VE tables and work the spark tables a bit... once I'm satisfied that this tune is doing everything want of it, I will put it up as a base for all of you to work from on your own setups.

I really hope this can help a lot of people with pre2k LD9's with boost. We've waited a long time for a solution... and while this one probably is far from perfect, it works a whole hell of a lot better than a 1 bar map sensor and an FMU.

I don't / can't do tunes anymore for people due to time constraints, etc... so I figured this was the next best way to contribute to the community.

I can't wait to hear about people having success with it!
