That's why they pay me the big bucks...wait...is $14k/year below minimum wage?

 

Thanks guys, that makes a whole lot more sense and explains why I was so confused. So I will obviously need 2 bar, maybe 2-3 bar. And the 98 pcm is only useful up to 2 bar, unless you add a MAF pro or other supplemental fuel control. So I could get away with a 2 bar sensor and good tuning as long as I don't plan on running over 14.7psi of boost.

Well, that kinda puts me in a predicament because on one hand I probably won't need more then 14.7 psi on a 402 on the street but on the other hand I would hate to want or be able to run more psi and not be able to.

You always think a certain amount of power is enough until you have it, then you want more!

 

LOL, ain't that the truth.

 

I dont get how forcefed's PCM reads boost so perfectly while everyone else on Earth has been trying to find a way to get thier PCM's to? I mean, forcefed, are you saying that your PCM reads how much boost you are seeing and actually corrects depending on boost level and air/fuel? If so, why is everyone so weary with their 98's?

It's actually a FAST 3 bar MAP system, not 2. I corrected the typo in my earlier post.
To do the conversion Speed Inc. used the following parts:
2000 Engine Harness
2000 PCM
Harness connector
GM PCM Bracket 99-UP PCM
adapter harness for PCM swap
I did not go to a 99 fuel tank, but the result is my fuel gauge does not work.

 

Cuz i'm special??

How many 98 owners knew that they could run 2 bar SD, how many are here in this post running a 2 bar SD tune?? Looks like only me. Blackbird posted a few months back that Rick@Synergy had a way to do it. I contacted him and he took good care of me and let me have a starter file to get me running with the 2 bar map sensor and in SD.

Its basically what a lot have said here, i'm running the car in SD and the VE table is chopped. Less resolution but more accurated when running boost through the car than with the MAF...I don't have to worry about the MAF maxing out anymore.

Rick@synergy sent me a nice starter file to work with, i've then did a lot of logging and fine tuning from there on out. I have no lean spots under boost like I did with the MAF.

The car is a lot more fun to drive, much more responsive. No funny dead spots in the tune and responds to boost damn near instantly. No spits or sputters, no surging while cruising and no lean spikes when getting into boost.

Its not like i've kept it a secret from anyone, I've told quite a few 98 owners that there is a way to run a 2 bar SD program with their 98 PCMs. I've even posted in the PCM section that I run a 98 PCM up to 2 bar with great results.

Is it nice like the 99-02 2-3bar OS's that HPT and efilive offer....NO..those have a lot more features, options to use to tune a blown car with. HPT/EFIlive will not offer a 2-3bar solution to us 98 guys because of the 98 PCM varies so widely. So this is/was the only option for us 98 guys until MAFT Pro shows to be a great alternative to run 2 or 3 bar.

Texas to NM is a short drive, come on over and i'll show you how nicely she behaves and how nicely she responds to boost....food and drink are on me.

As for those who want my file, email Rick@synergy nicely like I did. It'd be shady of me to pass out something that he gave to help me out without his permission. I rather him help you guys out like he did for me. But its been said here before about what to do with the VE table. Shucks there is even a post on EFIlive forums on how you'd go about doing it on a 98. It isn't perfect but it is a great alternative to what us 98 guys were offered from HPT/EFIlive.

Thanks for the lengthy response. I had heard rumblings from the EFILive guys that 2-bar was possible with at 98 but the details were thin. Turns out there simply wasnt any details...it just works. Good job, now hurry up and run that 10.999999 youve been trying to get! TH400's are cheap.

 

Jer ordered that Rock-on 4L60E and with it i believe he can finally hit his goal.... and still have OD
