Richard Bradley1436215368 Posted August 23, 2010 Report Share Posted August 23, 2010 Hi to all... I have just fitted a wire in G4 storm to a 1JZ VVTi in an S13 Silvia... have the car starting and revving sweet until it hits 5000rpm then it just stops revving and backfiring...Will not rev past it at all on any throttle...Sounds very like a bad ignition misfire (lambda reading a bit lean too while its missing) Tried wiring in Nissan coils in case I had a bad coils but no different. Tried batching injectors differently too...At the min I have them batched 1 3 5 to channel 1 and 2 4 6 to 2....This engine has 1 Igniter and 3 coils...I have the coils batched 1 6...2 5...3 4. Checked trigger errors and Im getting NONE at all... Both crank and Cam sensors seems to be reading fine. If i switch VVT off the misfire seems to be a bit earlier in the rev range... Very strange problem...Just wondering if anyone else has had any similar problems and any ideas of solutions to my problem would be great... Thanks...

Dtech Motorsport Posted August 24, 2010 Report Share Posted August 24, 2010 If you are running a standard igniter then this will be the problem one possible solution depending on firmware is to try setting ignition dwell to duty cycle i do not know if this will work and do not know what duty cycle it will require so some experimenting is in order or find someone with an oscilloscope to scope a standard setup and work out the values otherwise change the igniter and you will be away laughing Regards Dave [email protected] Quote Link to comment Share on other sites More sharing options...
