TPSacc question

Everything else looks good, I can clearly see the AFR on my wideband EGO variable going either to the extreme lean or extreme rich depending on which way the TPSacc wigs out.

TPSacc question

This is the exact same problem I have right now, except mine DOES change the pulsewidth drastically, it's enough that when TPSdot accel is turned on and I floor the car I get a violent cut out either due to a rich or lean condition, if I turn the accel enrichment off (high trigger voltage) then the ...

Alright, that clears things up a little I think.

Well, I know that you can use them together, but I'm wondering what does it take for an aftermarket ignition box to produce such a powerful spark and how does the VB921 compare? The Ford TFI system is supposedly very powerful but I wonder how the VB921 compares to it as well. The problem isn't ...

VB921 performance?

I couldn't find anything on a search, but I was wondering just how capable is the VB921 as a coil driver, certainly it will work good for most people, but how does it stack up against factory ignition modules and even aftermarket modules, as far as output. I realize it's limited to 7 amps, which is ...

When I had this problem I had left out the two top most resistors on the board, which are for flyback. Just a thought in case you haven't checked everything like that.

I'm having injector noise problems also, well, no problems now that I put a noise filter inline with the MS, but it was resetting ...

I figured it out, flyback wasn't working because I left out R32 and R36. DOOOOOOOOOOOOH!!!!!! I think I can get it now, I guess everything will be okay if I go to 30% or so and start from there?

I said up there that I could never get enough fuel under boost, I was pushing 200% VE and was still lean at 60% PWM. I never messed with accel enrichments but it was like a complete cutout and fizzle when hitting the throttle at 50% PWM, I have hardly any accel dialed in anyway, and it runs fine ...

V3 flyback problem?, current limit must be at 70% or above

I wasn't really sure where to post, but first I need to figure out if my settings are wrong for sure so I'll post here.

I'm running: MS-I v3.0, MT v2.25b717, Extra024s13c

I added all the flyback components as I'm using Bosch 35 lb/hr low impedance injectors, stock for a Ford 2.3T in later years ...
