  1. That has sorted it dont fully understand it but it works! I actually had it wired correctly at first, then when it first started, the tuner swapped the polarity as he thought it was wrong. a learning day for all! Thanks very much for your help and quick response. Cheers Willy
  2. Hi Adam I did lower the dwell as you suggested as it did seem to make a small improvement here is trigger scope log cheers Trigger Scope Log 2018-07-8 3;32;49 pm.llg
  3. it has the factory caldina coil on plugs with built in igniters. at one point i borrowed some brand new high output coils- with the same result. my tuner checked the trigger scope while on the dyno and seemed happy enough (its completely possible he missed something of course) I have attached a log and the tune file Log 2018-07-5 6;08;55 pm.llg rally car.pclr
  4. Hi Guys Ive got a problem with my car. It is a Toyota Celica Gt4 rally car with the Gen 4 3SGTE, it has had a freshly rebuilt motor and a brand new "milspec" wiring loom with all new sensors and electronics. ECU is a link Fury. we first put it on the dyno and has a misfire at exactly 4800rpm under full boost (19psi wastegate). we narrowed down the problem to cylinder 2. we have swapped around multiple set of coils, spark plugs, injectors and the problem persists on cyl 2. the compression is perfectly uniform across all cylinders.I also removed the valve springs and they were fine. i also ran separate wires for the injector and coil, directly to the ecu bypassing the loom. we also tried another ecu and updated the firmware. I then put a different wastegate spring (10psi) in and the missfire is still there, however not as aggressive. The misfire occasionally goes away but is there 90% of the time I hope you guys may have some ideas on what could be wrong (im now out of my paygrade) Cheers Willy
