Mspnp gen1 resets in full throttle/boost
 
Having problems with the ms1 pnp. Car acts/drives normally if I dont make an full throttle accelerations. When the rpm:s go 4000-7000 the meqasquirt resets itself for some reason. If I accelerate mildly and with just little boost it goes from 0 to 7000rpm just fine.

The car is an 93 eunos, its an ms1pnp and it has toyota cops + turbo kit. It has been doing this for a while...

Here's two datalogs if they are any help.

Sounds like a misfire.

Should be uploaded now. Tried today lower the boost setting but still the megasquirt resets...

+ It will do resetting more often on second + third gear, fourth and fifth it doesnt reset that often.

Thought it was the misfiring but I have tried the toyota coil on plug setup and the gm ls coils allso. Does the resetting with both of them...

I had massive issues with mij MSPNP back in the days with cutting out under boost. After trying everything I ditched the whole thing and got a DTA ECU.

Are you by any chance using low impedance injectors?

sasu` 09-08-2014 12:57 PM

The injectors are: EV14, 670 CC, 12 ohm, C, USCAR.

I checked the logs today but I was wondering what the idleDC is doing? It peaks when the megasquirt resets...

I dont have the idle valve anymore and the wires are cutted from the engine bay side.

stock coils? >10psi? gap your plugs down.

sasu` 09-08-2014 01:21 PM

Toyota cops / Ls coils. Tried with both with bkr7e 11 plugs (I think). Gapped them smaller also but it didnt help.

Battery terminals connected and tight?

Sensor grounds to ECU ground, NOT engine ground?
