  1. I had the exact same problem and eventually my fully built engine was destroyed.... no mechanical indication of what would happen.... weird dwell log , rpm dropping than only rising at 100% open throttle , melt spark plugs on bank 1-4 coil even though i changed 4 coils on that bank , 3 igniters and many different types of spark plugs , i even calibrated my trigger sensor at +180deg and used wasted spark coil no 2-3 on 1-4 and even then the same results , tha car was running fine untill 4000-5000 rpm when the dwell started to jump around with NO trigger errors at all.... Should i go shoot the guy who installed the ecu ? the guy who built the engine ? the guy who programmed it ? me for buying LINK than another ecu ?
  2. i have NO trigger errors , no errors indicated by the ecu , how can the dwell have such weird readings and not having any trigger errors at all ?
  3. Today i removed the cylinder head because last night one porcelain insulator broke from spark plug no4 and dropped into the cylinder while driving. The piston surface is ruined on the fourth cylinder as well as the engine head on top of that piston. Pre-ignition signs are very obvious , broken piston rings on cylinders no 1 and 4 and scratched cylinder surface. Is there any connection between dwell readings and this phenomenon ? Was there any way i could see that coming via the logs and avoid it ?
  4. Today i re-callibrated the trigger wheel and was ok , Checked valve clearance and was also ok , checked compression and had 150-190-190-150 and i suspect burnt head gasket due to water overheating, could the burnt head gasket justify the pre-ignition above 4000 on boost and the weird dwell readings ? thanks !!
  5. hello , I have a Link G4 storm installed on my toyota 4 cylinder turbocharged engine that runs stock wasted spark ignition and stock crankshaft trigger wheel 36-2, along with a KnockLink wired to the stock sensor but not correctly setup yet. The engine idles perfectly but above 4000rpm on WOT the car struggles to rev and while logging i noticed some weird dwell readings. Moreover the spark plugs of the first wasted spark bank 1-4 often come out with melted electrodes indicating pre-ignition while the other two of the bank 2-3 always come out in perfect condition. while the dwell is configured from 1.4 to 2.2 along the rev and voltage range there are readings of 0,05 as well as 3,81. I suspect wrong trigger calibration or valve clearance issue even though the smooth idle does not point towards it. I have attached one log file. Any help would be appreciated , thanks. 1.txt
  6. I have tried that but it didnt work ... the settings i am using are 57600 Baud Rate and Datastream Mode to OFF. We miss the DisplayLink so much.... Please help !
  7. I have a 5efte toyota starlet with link G4 storm and extensive modifications on ignition etc , everything works fine though i found it tough to get the engine start for the first time since there are no base maps out there. The loom provided is more than enough for you to attach it to the factory ecu loom , and installation is pretty easy.
  8. hi , i just updated my Link G4 to the new firmware and the DisplayLink attached stopped working. Communication is ok but the problem seems to be firmware incompatibility , the error message the DisplayLink displays is 'Update ECU Firmware'. There was no warning for DisplayLink incompatibility after the update in the Firmware changelog, Have i done something wrong ? I suppose not , I would appreciate some help , thanks.
  9. Problem Solved , apparently the coils should be configured as rising edge and not falling... that seems to be the cause of the overheat.
  10. Thank you Cameron for your reply, After a lot of cranking and A/F monitoring i managed to maintain a smooth idle but i am facing trouble with my Wasted Spark coils Overheat. Before installing the G4 ECU I replaced the distributor ignition system with Oem Toyota Corolla 4EFE crankshaft trigger wheel and the OEM Ignition coils , wired them accordingly to the ecu and callibrated the trigger signal. Therefore the engine cranks and starts fine but after 3-4 minutes of idle run the coils overheat and eventually die and i have already replaced 1 of them. Some guy told me that it was the Dwell setting but that is already too low (3-3,5ms). The coils i use have the Ignition module embeded and are falling edge (from what i figured out after some tests). Is there something i should alter in my ignition settings that could solve my problem?
