Adturb Posted March 12, 2016 Report Share Posted March 12, 2016 Help! I have just converted an Evo 6 with EvoLink 4-8 G4+ to direct spark, but it's not working.In PCLink I have changed the spark mode to direct from wasted, moved the wires from Ign 3 (Pin 22, now Ign 5 pin 35) and Ign 4 (Pins 20, 32 & 34, now Ign 6 on expansion harness) and run in a new loom for coils 3 & 4 but the car will NOT start. It is as if the injectors and ignition are firing on different cylinders as there's plenty of popping out of the exhaust. When I refit the wasted spark harness and change the spark type back to wasted it fires up with no problems? The ECU is running the latest firmware.I have checked and double checked the coil harness wiring and I am 99% sure it is correct (Each ignition output was put into test one at a time and a spark confirmed at that cylinder, then checked with a multi meter. + and - pins are stable at 12V, ignition wire to +12V fluctuates when in test) so after a couple of hours of testing and double checking I'm hoping that someone can shed some light on the issue?!?! The only odd thing I can could see in the base map settings are that the Evo 4-6 has a different trigger 2 setup to 7-9, however the cam signal is the same on 4-9, so why this difference of rising and falling edges? I have tried both settings by the way, and no improvement. I have already completed this exact same modification on a G4+ Evolink IX and had no problems at all. I've attached the Direct spark file (Car won't start) and a modified version of this file back to wasted spark that DOES start the car when the original coil harness is refitted. I am hoping I have missed a setting somewhere, I can't find it for the life of me.Thanks Ads Lambda1 DirectSpark_Wasted.pclr Ads Lambda1 DirectSpark.pclr Quote Link to comment Share on other sites More sharing options...
Scott Posted March 14, 2016 Report Share Posted March 14, 2016 Have you re-calibrated your base-timing? Possibly it worked before, but only because the setup was wasted spark. Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 14, 2016 Report Share Posted March 14, 2016 I suspect you are 360° out. Try adding 360 to your trigger offset. Quote Link to comment Share on other sites More sharing options...
Simon Posted March 14, 2016 Report Share Posted March 14, 2016 Go with the trigger setting that works for wasted spark.As Adam mentioned you could be out by 360 in the timing offset which will give you spark but it will be on the exhaust stroke for all cylinders.

Adturb Posted March 18, 2016 Author Report Share Posted March 18, 2016 Sorry for the delayed reply, really appreciate the fast response and advice. As soon as I can try it out I'll feedback the results......FYI the car runs fine on wasted spark with either trigger settings of 'Evo 4-6', Trig 2 Falling, OR 'Evo 7-9', Trig 2 Rising. So far as I know 4-9 all have the same cam and crank sensors? Quote Link to comment Share on other sites More sharing options...
Scott Posted March 21, 2016 Report Share Posted March 21, 2016 According to the information I have access to, the width of the teeth on the cam are different between our 'Evo 1-6' and 'Evo 7-9' modes. Adturb 1 Quote Link to comment Share on other sites More sharing options...
Mendiesel Posted April 1, 2018 Report Share Posted April 1, 2018 Been searching and though I’m running a vipec v44/v88 top board it was relevant to me I’ve change to direct spark and imported a dwell table to suit the coil packs. The car does run but now it very hard to get started I’ve set the trigger offset from 5 degrees to -355 seeing as it was probably 360 degrees out once it does get started from holding the throttle fully open it runs fine Any ideas why it would be so hard to get started now?

Adamw Posted April 1, 2018 Report Share Posted April 1, 2018 Most likely dwell related I would say. The Evo has a low tooth count trigger so will need significant cranking dwell. Can you post your dwell table and what coils you are using. Quote Link to comment Share on other sites More sharing options...
Mendiesel Posted April 1, 2018 Report Share Posted April 1, 2018 Thanks for the quick reply mate, spent a bit of time on it last night and as embarrassing as it is, I took a 12v switch to the relay which ended up having low power as crank so my ignition was extremely weak. Problem is solved but I’ve found another but that’s a temperamental wire at the ecu which I’m trying to trace. Quote Link to comment Share on other sites More sharing options...
