Mspnp2 No start

Post by LostOffspring »

So I just recently installed the mspnp2 in the car and hooked up the WB, IAT, and Map sensors. All of them seem to be working fine but the car won’t start on the DE base map.
Its as if the distributor is 180 off but it runs fine on stock ecu. Is there something obvious im missing here?

Engine: Stock s13 ka24de stock dizzy no trigger wheel

Thanks
Jon

Have you set the trigger angle? Checked battery connections and engine grounds?

Update: So I had a couple issues causing the no start. Lower timing chain was a tooth off, and I left the MAF plugged in whilst using speed density.

I did end up setting the trigger angle and had some issues with the ecu reading the coolant temperature incorrectly (fixed by changing thermistor values).

Currently struggling with getting ut to start smoothly. The kick back is crazy and I have to give some throttle for the car to start. I'm using the DIY trigger wheel.

shouldn't be kickback w/ DIY trigger wheel. Post your tune file and one of us may be able to look through it and help.

I'm just going to keep updating this so that maybe someone can learn from my ignorance. I think the kickback may have occurred because I had my trigger wheel arrangement set to "single wheel with missing tooth".
