it wont start....

it start well with the old ecu and dead afm even if the engine is hot....

please do help

 

The answer is simple: you need to tune the ECU to your engine.

 

read the owner's manual for the PS1k, specifically the water temp correction map and cranking maps. it's long and drawn out explaining how to tune, and we're not paid to do so so either do the homework and tinker with it while saving your original map or take it to a nearby rotary tuner, keyword "rotary" tuner.

likely your hot cranking maps are either too lean or your coolant temp sensor is dead, dying or has a wiring issue. the 500 rpm map also plays a part but if it starts just fine when cold i wouldn't dick with it.

 

To be honest, if you don't know, you should find someone local with Haltech experience. At the very least, head over to the Haltech website and read their manuals on the ECU and basic tuning. That will get you familiar with the process and the steps needed to make basic adjustments.
