Hi All: After reading all the articles on burning your own PROM, for some of us this is much too complicated. I really don't want to get that intimately involved with learning all the acronyms and doing trial and error chip burning. I would prefer just to buy one for my model of car, apparently from a private source since the commericial ones are reputed to be somewhat worthless. One would think it would be much easier to go to an expert with a similiar engine set-up and just order a chip from that source. Does this make any sense to some of you or am I just being a whimp and should bite the bullet and try to program my own PROM. (THIS DOES APPEAR TO BE TOO TIME CONSUMING AS WELL WHICH IS THE REAL ISSUE)
Thanks,
Laser

 

what is wrong with stock chip? as the level of mods increase the opportunity to get it right from mail order burner are inversely proportional. maybe a board member lives nearby that could lend a hand but that is iffy.

 

Ronnie, good point on not getting a universal fit. I'm sure changes need to be made to increase performance, cooling fan temps and shift point speeds. This is a TPI 350 by the way.
Thanks,

It sounds like you want quit before you even get going. If you make up your mind about anything, before trying it, well, you will always be correct. It's really easy not to even bother trying.

Do you suppose he drives, the same exact way as you do?. There's a huge difference in what one driver calls OK, and what another does.

For the money you'll WASTE, you could buy all the stuff to do your own. Not to mention that if change anything else in the future, you'll just be saving more.

Sometimes you just have to dive in, and *just do it*.

 

Grumpy, thanks; just call it fear of the unknown! What components are absolutely necessary to do a burn job? If I get this right, does an updated tuner program over write (new chip of course) the OE PROM and is the other option to program your own specs into the PROM? IF so, are you using the specs on the tuner program to more or less guide your spec changes into the new PROM? Wouldn't want to to blow the engine by inputting unrealistic specs.
Thanks,

you need to datalog(winALDL or tunerpro rt 4.0) first to determine what you need to change such as main fuel tables/choke etc.

and/or datalog with WO 02 to calibrate the AE (aka pumpshot) and possibly PE or WOT A/F.

then we burn a new chip with some (not a lot) changes and repeat above. maybe 100 times? now i would suggest we start with stock GM bin for your or a similar platform car.

but b4 all that study, especially yhe stickies. Intro to Prom Tuning

 

Ronnie, thanks, I need to learn all the definitions first.

man your soooo lucky im gettin ready to start to dive into the world of diy prom for the very first time also and i know absolutely nothing about it but i wanna learn.....you dont know how lucky u are to have a l98 which from what ive seen most articles or stickies on here r wrote about try being like me and having a l03 and see how much u get in the stickies for your ride...lol...well good luck and the guys here will be able to help u alot and even if it is time consuming you will have learned some thing invaluable.

 

Hi there, I'm still working on re-arranging the cold air system since it is so befuddled at the present time. Then I may play with the chip, mostly making minor mods to the spark advance, fan temps and WOT pump shots.
Aloha,

If you read the stickies, take your time, you'll be off to a good start. You start with a stock .bin file, and then slowly make small changes, and take detailed notes. Taking notes, and looking for trends is 2/3's the battle. The notes will tell you what the engine likes, and from there life is easy. As you develope the intial skills and get familiar with what'd going on, then you can set your own goal for what you consider as being *good enough*.
