Thread: AE Correction vs TPS with progressive Terminator TB.

  1. #1

    Default AE Correction vs TPS with progressive Terminator TB.

    I've driven around 200 miles on my Terminator/HP ECU install. Got the setup used with a new harness and WBO2 sensor. I’ve been having driveability issues with acceleration. I gave it some time and hadn’t touched any AE settings, but it’s still nasty. Super lean spike and if I stay in it, WOT, it’ll pop and sputter and SLOWLY clean up. Seeing up to 30:1 AFR?!?!

    Today I Transferred Learning To Base with a table smooth then manually smoothed the graph in the WOT and heavy acceleration areas. I pulled AE vs TPS RoC Blanking from 15 down to 13. Also adjusted AE Correction vs TPS to go from 250 - 0 left to right. It was 300 - 100 before. All of that cleaned it up considerably, but I’m still having some of the same. I can accelerate more aggressively now, but WOT is still nasty.

    Here’s the question: The linkage on this throttle body as I purchased it, is progressive. Secondaries just start to crack at 15% TPS and I have it setup that way in Engine Parameters. So...should I adjust my AE Correction vs TPS Correction table to account for this? And if so, what’s the best way to get it close and read datalogs to hone it in?

    I've never had the AE vs TPS RoC Blanking in the double digits.

    That's not much of a progressive secondary throttle linkage.

    Why haven't you tried? This is user programmable EFI.

    And if so, what’s the best way to get it close and read datalogs to hone it in?

    I’m still having some issues. I understand carburetors and in a basic sense, EFI. When I go WOT, 100% TPS, the car spikes to 35:1 AFR & dies. I’m thinking my AE Correction vs TPS is the issue. Maybe V5 is different than V4 here? I’ve never used V4. There’s a solid line across the graph at 100% then the graph goes all the way down to zero below that. Reading the manual, it seems everything below 100 subtracts % of fuel from the Base Fuel Table. If that’s the case, at 100% TPS, I’m pulling all of the fuel, which would make sense considering what’s happening. Initially I believe my graph went from 250-100%. I read somewhere it should be going from 250-0%. Do I really want it to start pulling fuel around 60% TPS? I’m sure there’s something I’m not understanding.

    That's not usually the case. The WOT area of the Base Fuel Table could be lean. Is the Learn Table populated with values?

    No, it's the same parameters.

    Slowly getting things sorted out. Still have a lean spike, but it cleans up and accelerates much quicker now. I’m going to switch from a dual-plane RPM Air-Gap on a 1” spacer to a single-plane pretty soon also. What’s the best method to post up a Global File & Datalog to share here?

    If posting your Global File and a short datalog of a driveability problem for us to analyze, first review the datalog and
    inform us of exactly where in the datalog (time/seconds) the problem occurs. Someone will look at it and offer advice.
    Read the end of this post for instructions on how to email Global Files & Datalogs.
