Thanks a lot for help. I will adjust the dwell table. My sparkplug gap is 0.6mm, i believe i could set it to 0.4mm also because i use E85 105 octane racefuel that is 30% "WETTER" than gasoline. It is not easy to se the camtooth without pulling of exhaust/turbo/intake, but it easy to adjust the sensor. I have found another tuner who is experienced with vipec, he has his own dyno and a Evo1 or 2 with 700hp. He told me that that the LS2 coils also should be grounded in the heads, not just in chassis as today. I will deliver my car to him on Monday with a printout of your replies. He will start troubleshooting, and if he finds and fix the problem, he will make it raceready. You may also check facebook.com/turboroadster for updates.

What do you have for coils/ignition system? 4x LS2 coils, with 36-1 on crank and VR sensor. Gap set to manufactors spec 0,2 to 0,4mm (with endplay) How are the triggers set up - is the cam tooth well away for the gap on the crank etc? I am not sure how Cam tooth is positioned related to crank. Have you confirmed the polarity of the crank sensor is correct? It is connected as instructions. Have you ever had an oscilloscope on it to confirm if there is a trigger problem? yes, on my previous crank trigger system the voltage varied more than 50% on the teeth. Thats why i changed to this new crank trigger, but it was no difference. I had to thrust our "dynoguy" for the mapping, i have no clue myself and he has a good reputation for doing it right on my friends cars. I have bought all ECU, ID injectors and the wire harness from him also but now it seems that he is not able to find out what is wrong, and its difficoult to get good support. Maybe i should find another tuner? Is it easier to correct this if i make a Hall sensor instead of VR? My friend with similar engine and ECU gave me his map for comperance. Is there anything in these setups that can contribute to my problems? Ign.table 4D ignition: Me=On Friend Off Trigger 2(cam sync) Pullup: Me= On, Friend=Off Edge: Me=Rising, Friend=Falling Digital Input Pullup resistor: Me=Off, Friend= On. Arming Threshold Me= 0,5 to 6.0 Friend= 0,2 to 4.0 RPM Limit End cut: Me=100% Friend= 75% Start Cut TP100%: Me=60% Friend=65% Start cut TP Low:Me=0% Friend=65%

Hi I hope someone can help me. Car is old vw beetle and i try to get more than 500bhp out of it. Had struggles past 3 years, but i really hoped to join my friends next weekend for my first dragrace. On the dyno, with load, the car is "buggering" or misfires. My "dynoguy" says there is not clean enough trigger signal, so the ecu does not now exactly were crank position is and misfires. I have tried 3 different triggerweel setups with VR sensors, and had several dyno attempts, also rerouted the shilded trigger cable so its far away from power wires. I have a friend with same type V44 and i borrowed his ecu last night, but could not hear any approvements or see any on the log. I have log files if someone could look at them. My "Dynoguy" also told me to log RPM-rate, so i did. But was this data mean? I really hoping for help. Edit: I Have attached engine map and log from yesterday. Just started it on trailer. min-ecu-Log 9-08-17 9;24;20 pm.llg Turboroadster-09-08-2017.pcl
