    I doubt low 7's as the fastest stock suspension Fbody record on boost is around 7.3 and on the bottle is 7.7 IIRC.

    That's an incredible 60' out of a fwd car to run an 8.6 at only 159.

    Fastest 1/4 mile with stock PCM and HPTuners?

    I was curious if anyone knows what the fastest 1/4 mile time is with HPtuners software in the car?

    I had my buddy Steve's car running 8.8's @ 160 MPH on nitrous before switching him to aftermarket...

    He is using a new Windows 7 mini laptop to log. He is going to log a pull with his old laptop that runs windows xp and see if it reads right or if it's something else.

    Got a link to this explanation? Can you verify that the number displayed is actual and not commanded?

    Not really. The car is running commanded timing (according to the scanner) at everything but WOT. At WOT, it's dropping about 2* for most of the pass. Even if I were to put a balancer on with timing...

    The tune and logs are on my buddy's laptop as he bought his own copy of HPtuners. I will have him send them to me and post them ASAP. I am extremely competent when it comes to tuning the fbodies. I...

  11. What sensor is used to determine actual timing in a log?

    I have this problem and it's only the second time that I have seen it. The other guy switched to an aftermarket PCM so it was never resolved. The problem is that we are getting 2* less timing in the...

    I replaced the default Boost custom PID formula with the following ([PID.11]-105)/7 on v.2.23

    This should work for a 2 bar OS. Atleast it works for mine (only in boost). Disregard negative values...

    I've considered that and am also considering the megasquirt II. At this stage of the game, I've just about outgrown the stock PCM.
  15. I'm running a front mount turbo setup....

    I'm running a front mount turbo setup. Regardless, how is boost from a blower different than from a turbo?

    The limitation is that the only custom OS available for the 98 PCM is a 2 bar. 99 and up...
  16. What are the other proper parameters? Just pop in...

    What are the other proper parameters? Just pop in the 0-5v 4 bar map and cut everything that references the MAP entry and exit in half and rebuild the VE table? Or is there something else?

    How about using a 4 bar map sensor and splitting it in half?
  18. Can the 98 2 bar SD OS use a 3 bar map sensor and scale?

    Basically I am stuck with a 98 POS PCM. I am currently running the 98 2 bar OLSD OS with a 2 bar GM MAP sensor and it worked great for the stock bottom end turbo build. Now I'm going forged and want...

    I'm not really clear on what you are trying to do here. I do know that you dont want to change the stoich or it will throw everything off once you put it back. Why can't you just disable the MAF, set...

    Since I am running in Open Loop, can I change the OLFA table in the WOT MAP area to match my PE commanded fueling? To clarify my question, do the PE table and OLFA table work together or independent...

    That's because it is falling out of PE. If you look at the PE table, it's flat across the board up there. This is all part of the same problem I believe. No WOT stop modification. This is the same...

    Timing Spike @ WOT

    More wacky problems from this same car that will not return to idle routines 100% of the time.

    Here's the latest. We took it to the track and were doing some nitrous shakedown passes on a small...

    Thanks for the info Chris. I will try that out. We ran another ground to the motor as well as grounding out some wires on the PCM. This seems to have helped some but it still doesn't catch the idle...

    In theory, if we could get 5V power and a solid ground from another source and we just hooked up the signal wire to the PCM, should it work? We aren't there yet. We are adding another ground to the...
