How Much Power Is Possible Turbo And 98 Pcm???
I'm using the 2 bar "baro" sensor from the cobalt.
Drivability suffering??? Please
I drive my car everyday and she is more responsive with then she was with the MAF. She responds to boost and boost changes instantly...fuel is there, no lean spots like there was with the damn stock map sensor and MAF running the show. With the maf/stock map sensor I always had a lean spot when entering boost.
With the 2 bar map sensor and my car running in SD its been great.
To go to the 99 PCM is too much of a hassle.
You have to buy
99 PCM
99 Harness
99 Gas tank
Evap system is different as well...
If I had to go that far i'd go BS3.
2 bar "baro/map" sensor was 29.00 bucks and now the car "reads" boost just fine and is a sheer pleasure to drive around town now.
Newbies, back off with the attitude, Kyle is a great guy and had never disrespected anyone here in the FI forum.
The MAFT-Pro is going to be the "must get" item once we see some results. With Harlan and Stenod Racing doing the testing on it, it'll be close to perfect as one can get if still running PCM's from GM.
PN for the Cobalt Barometer sensor is 12580698

Just Talked to Stenod.... He's having a bad Day.. Here's one for ya Joe
The repinning is the Most $$ North of $500 for it alone. Alot of HRs doing that.
Then you will need a 99+ computer. Not sure on the $$ There.
New connectors.... we didnt get specific because he had to go, i just wanted to get a run down on it for you guys.
Kyle
Yep there is a lot of $$ to be spent when doing that conversion....plus repinning a harness....F@#K that...talk about a PITA and time consuming.
I just had to reach back behind the manifold, disconnect the map harness from the sensor, pull the sensor out, get the new sensor, put the rubber "gasket" from the old sensor onto the new sensor, clip off one of the mounting tabs on the new sensor, pushed the new sensor back into the intake manifold, connected the harness...and was good to go.
DL'ed my 2 bar tune, disconnected maf, disabled a few SES light codes and started tuning

Thanks Jer.
Kyle,
I think John was just responding to the over-reaction post you made when you were apparently offended by his "patch-job" post. I don't think that he meant to offend you but it is what it is. John might not have a ton of posts on here but he is a good guy who happens to be a quite good HPT/EFIlive tuner also. We are both new to the FI tuning world though and are trying to learn.
Anyway, it is all application specific and like I said earlier if something works for you on an apparent mostly-race setup thats great but it doesn't mean it is going to work for everyone. I also think you may not realize that some of your posts come across as "this is how me and Stenod do it so it is obviously the best" kind of way.
By the way, thanks for EVERYONES input on the matter.

I think I also forgot to list a 99 cluster as well...more $$

Verdad Gallardo Forcefed98, how much boost are you running, pump gas vs race gas?
I guess the entire reason for this thread is that I don't want to put in the 402, install a T88 and be cruising around or on the dyno tuning and suddenly run out of mapping in the PCM. I don't want to be in a situation where I could run 15psi on pump gas but can only run 13psi because I have reached the limits of the 98 PCM. If the common opinion is that I can run 15 or so psi without reaching the limits of the 98 PCM or adversely affect driveability then obviously I will just use the 98 PCM. IF there is a chance that I will have an issue I would rather change it now rather then run into problems later.
I have a 99-up tank and pump, can get a 99-up harness and PCM for $100, and a cluster for $70 so the only unknown expense/hassle is the thought of changing/finding the dash harnesses I would need for the swap. That is the only thing holding me back at this point from making the swap and why I was trying to see if I really needed to do any of it.

Just kinda sux.
And Kyle, good luck with the MAF T Pro (and the car BTW), I'm watching for your results...

Im sorry if you see some of my posts going in that direction. I was just going off of what i know they have done.. never meant to put anyone down in any way.
I do plan to do quite a bit of street driving and i know a few others that will be trying it out also. Each can give there input on how this setup reacts to each persons own driving style. All i wanted was for others with a 98 PCM to know that there is a way to tune above a 2 bar MAP.
Sorry if i misinterpreted it.

Email him again. He's been pretty busy the past two weeks. If not give him a call, the webpage has his phone number.

I've gone as far as 18psi on the dyno
But that was due to us messing the BC. A/F was still in the 11.8 range.(overly safe tuned for 12psi)With the 2 bar set up you are "limited" to 14-15psi. If you want to run more boost than that, watch your WBO2 and keep manually adding in fuel there after.
I'm trying to boost to 15psi on meth. I ran VP MS-109 unleaded at the track on sunday because my meth kit is waiting on a check valve to get here.
BUT if you already have most of the stuff to do the 99 conversion, go for it. If you didn't i'd say do the custom 2 bar stuff and see how far that gets you(2bar map sensor is cheap). I'm really wanting to run the MAFT pro but will hold off until Kyle gets some excellent results and some feedback from the guys setting it up for him. If its easy to set up and tune I'll be buying it.
I like the maft pro because it'll control a boost controller too from what I've read.

I mean 2 bar is almost 30psi correct? maybe I am understanding something wrong but I see alot of people trying to run 2-3 bar setups but I don't see anyone running over 30psi! What am I missing??? Or is it that when you anywhere close you should upgrade to more bar? The whole bar thing is confusing...
I'm not sure what 3 bar is...30-36psi??

Ok here is how it is....
1 bar.... (stock) reads from vacumm to 0 psi.......
2 bar is from vacumm to 14.7 psi....
3 bar is from vacumm to 29.4 psi.....
1 Bar = 1 atmosphere

Well...technically you could think of 1 bar = 14.7 psi. Not 14.7psi of BOOST, but just air pressure. See, ambient air pressure is 14.7psi...so 1 bar = no boost. 2 bar = amibent + 14.7psi or 14.7psi of boost total. That's confusing though...but at least you were kind of right
