Thread: Low throttle in gear bucking

Its double grounded, 1 to the ECU and one to the intake manifold. Both solid connections. I could try grounding both to the intake manifold perhaps however I dont see this MAF possibly being grounded any better than it currently is. All are spade male/female disconnects with heat shrink, solid crimping etc. I made sure of it.

There are also distinct differences with the Water Temp RPM Gain values. That may have something to do with the Idle? Im going to fiddle with different things and see what I can come up with. Hopefully I dont break something.

I always cut the harness ground then reground the maf to the main ground on the frame rail.

So I should try grounding both to the frame rail instead? Both as in the 2 ground wires the n60 maf has.

both grounds should be hooked together. The maf sensor is really sensitive and thats why I am going with a map sensor.

Hooked both together and grounded to chassis, made no difference unfortunately.

Update: Jerking problem fixed. Took original de maf bin and changed the VQ table and Inj K value to compensate for N60 maf instead of using one of the other bins that was already for the n60. Now my engine braking is smooth as it used to be.

Idle however is still being tricky. Ive never been able to get my car into timing mode via the rain dance so other than messing with the Inj K value at this point im not sure a good method to solution the idle.

Note: No air/fuel readings currently so that makes it more difficult tuning. My header has a crack in the weld so I am waiting until I replace it to have the bung welded for the wideband.
