UCD15R33

hey ppl I need some advice on whats going on with my r33. Yesterday i took my car for a dyno now six months ago it ran 250 hp no worries and what was with a stock fuel pump and inject and coils and pod. Yesterday i took the car back because we put some more boost into the car and a 040 fuel pump took see what happen. Now about 2 weeks before it have a tune and it ran 234 at 10psi cause the fuel pump was not working properly. So yesterday it ran a 218hp with new fuel pump and 14psi boost. the air fuel ratio was fine it was bout 10 or 11. One problem we think it might be is that turbo has a big whistle before boost it doesnt sound healthy. So any ideas Thanks

Well after try everything we went back to the ecu wireing harness on the stock one. it turns out that the pins in the stock harness one was bent. Thankx guys

yeah taken everything back to original setting but still not go. Miss fire still there and still cause problems.

Hey PPl I Need help asap. I have just spent a fair wack for cash on my r33. At present it’s got standard coils, high flow turbo, and 3 inch exhaust pod filter and just put a 040 fuel pump in yesterday. It ran a 13 at 8psi about 3 months ago. Yeah not bad. yesterday me and a mate put the 040 pump in and after alot of ppl tell me not to get an Ultimate emange I got one anyway. So we change the harness as we were told and put it in. It ran fine after a basic set up leaving everthing to standard. After about half our running it went to shit. It startd missing pritty badly. So we turned it off and went through how it was to be set up. After bout 30 minutes of stuffn around we try starting and nothing it would crank but no go. so we did this till the battery died. As i had to go home it was eaier to put me pride and joy on a tow truck home. Got home and unplug the e-manage and put to stock ecu back in and it work fine better even to a degree no missing nothing. Reset the emange and tryd again and got it startd but still no luck. it keeps missing. Does anyone have a idea why????? T

how do i get to the data sampling? i don't have that icon on my screen? all i have is a data logging, but no the one that shows the maps. it is just the one that graphs it.
