Sorry for delay in response, I have now spent some more time on this and set the base timing correctly. When the fuel load source is set to off the engine will start and idle fine around 1100rpm, it will struggle to rev as there is no load measurement. When i set the load source to MAP, it struggles to even idle. It will idle around 500rpm and hesitate and cut out. it also will not take any throttle. I have attached log files with no load measurement and when it is set to map. I have calibrated the map sensor and it reads 14.5psi when engine is off and around 6psi at idle so MAP sensor seems to be working ok. Ive attached the tune also which is just the base file with not much adjusted. Any help much appreciated. Thanks h907poj-no-map.llgx h907poj-map.llgx r32gtr h907poj v2.pclx

Hi All. I hacve installed a G4X to a nissan R32 GTR, followed the set up to the best of my ability but on start up it doesnt run great. With the fuelling turned off it turns over fine, but once fuel is on it struggles to turn over at as if the starter is jams or the ignition is off causing it to ignite too soon/late. It will eventually run at part throttle around 2500rpm but runs rough. The Engine is standard apart from HKS induction kit and cat back exhaust. I have tested the injectors and they all pulse. I have set the throttle position and also calibrated the MAP sensor. The fuel pump works on all 3 speeds. I have tried to record the trigger scope and also log when it was running to see if anything jumps out as being at fault which I have attached. Thanks for any help.
