Thread: Issues over 3,000 Rpm

Hey guys just finishing up my 93 SE-R added a t25 turbo I'm using the stock MAF and 370cc injectors with a calum ecu tuned by JK tuning. I'm having an issue with the car going over 3k in any gear if the car is in neutral it will rev all the way up to the limiter but once there is a load, the car will not go past 3k it will buck and shut off. There are no codes and the car seems to be running fine. I've changed the MAF,Dist Cap and rotor along with the plugs and wires anyone have any ideas what could be going on ? The TPS seems to be fine when I checked it via ECU Talk. I have a log also from when I drove the car the other day if anyone is interested in that as well.


Thanks in advance Mike

Sounds like the coil to me

Limp mode?

i was having similar issues with my car lately, its not turbo yet.. but whenever i'd try to get on it or use any gas pedal at all it would basicly stall the engine..

replaced the fuel pump problem gone.

The car has a Walbro 255 pump

you should try to do some sort of datalogging.. thats how i found my problem, the wideband would go full lean everytime the problem happend. even if you dont have a wideband you can still datalog things with datascan or some other consult type program

I did log the car. Nothing seemed to pop out at me I sent it to JK to see if he see's anything wrong.

does it act like a rev limiter?

Sort of the car will buck and then shut off if I don't get off the gas fast enough.

that sounds exactly like the problem i was having..

how do i check out your log?
