I am actually doing a conversion to a two bar right now. I am wiring in a 2 bar and just reconfiguring all the tables to make it work. So hopefully this will work and work correctly.

Can you keep me posted on how everything goes... I was told that I had to swap out to a 99-02 pcm and guage cluster and repin the harness to make this work??? Are you just putting on a 2 bar and rewiring it to the 98 pcm?? Let me know. Thanks

Yes, instead of reading off the 1 bar stock map, I am puting in a 2 bar map and working all the tables to work with it.

Rick let me know how it goes, will a repin on the harness work?
I cannot get my buddy's 98 to run right under boost, if it had a later model pcm I could get a 3 bar upgrade.

Ok, it works. Got the 2 bar in and was on the dyno today going through all the cells. I found since you add a 2 bar from a 1 bar stock, you have half the value in the table, which is fine, and you will now find that 50kpa equals the old 100kpa. So now when I start going into boost, I go into the 60 and up kpa values. Works great. Just alot of VE work to do now. It will take a good amount of hours to now rescale all the tables. But worth it. Now I dont feel like I have to hold back on this 98 turbo car. You will also find that because of the 2 bar, you have to double your VE values. So now there are some crazy values in the table.....but like I said, it works. And it works good.

Hey Rick how long did it take you to repin the harness? Did you have to extend any wires? Can you share some info on how you did this? Thanks...

Thats the thing. I did not repin anything. I just bought a 2 bar map, bought the connector for it, wired the new connector in to replace the old MAP on the stock harness. So basicly the ECM is now reading the 2 bar. Thats it. All the rest was done in the program. It takes some work, but it worked so good, its great. Brings new hope to the 98 guys. I know I wont go back to using the MAF for this turbo car.

The reason to upgrade to the 99+ pcm is because it gives you many more options as far as tuning and custom 2/3 bar Os's are concerned. Yes it can be done the way rick said but there are stupid things that will hold you back like the sec ve table and not having the use of your high octane and low octane you will be stck in the low octane table permenantely.

I've never looked at the schematics... can they be repinned successfully? it seems that they would be too different.

Yes, it can be done. Kieth of HPTuners did it and I will be doing our Z28. It is a bit involved, but with patience and time, it can be done.

Yes, it was that simple. And HummpinSS is right, its more useful in the tables to go to a later year, but for cost and ease of use, it was this easy for the 98's. And during the dyno work, It was using the Correct parts of the VE table since it is reading half value.
