Rasmus Posted June 15, 2023 Report Share Posted June 15, 2023 Hi, I'm having issues with getting my pnp G4X working and I have no idea what the problem is. The car starts with the oem ecu but runs poorly due to 1000cc injectors. But with the link it starts once (and run for 1 - 5 seconds) and then it doesn't want to start again, but if I try to start it again a couple of hours later it will fire up for a couple seconds again. I'll attach a log file from when I tried to run it a couple of times, I got it running once during the recording.

koracing Posted June 15, 2023 Report Share Posted June 15, 2023 Post a copy of your tune. If you want I can remote log in and see if there's anything obvious as well. Just PM me if you want to set that up. Quote Link to comment Share on other sites More sharing options...
Rasmus Posted June 15, 2023 Author Report Share Posted June 15, 2023 Here is the tune that I am running atm, it's just the st185 basemap with master fuel set to 7ms instead of 14ms to compensate for the larger injectors.

Hodgdon Extreme Posted June 15, 2023 Report Share Posted June 15, 2023 I think first order of business is getting MAP and WBO2 functional. Is the TPS functional? How about the IAC? Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 15, 2023 Report Share Posted June 15, 2023 Yeah, MAP sensor not working is the main issue. This means there is no fuel being injected so you will only get a tiny bit of fuel from the pre-crank prime. As far as I know the MAP sensor pin doesn't vary on the ST185 and all cars the ecu fits should have one so it may suggest a wiring issue or dead sensor. Also, the map you attached doesnt match the data shown in the log so it would be more helpful to attach the actual log from your ecu. I would also suggest you put the master fuel back to 14ms for a closer starting point for 1000cc injectors. Quote Link to comment Share on other sites More sharing options...

Was wondering exactly what I was seeing in the log... Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 16, 2023 Report Share Posted June 16, 2023 Yes, if fuel equation load source is set to MAP then MAP is effectively a multiplier. Multiply PW by 0 MAP = 0PW. Quote Link to comment Share on other sites More sharing options...
