Evolution55

Thanks for the reply. So it all seems normal then for these. So it's time to take the next step and go E85.

Hi there, This isn't really a G4 issue but I have a G4 plug in in my Evo 1. I'm getting detonation (hearing det on link knock block) at around peak torque rpm range on wastegate boost. Wastegate boost is 18psi. Fuel is BP 98 (fresh fuel). Engine is very stock and only making 217kw. Turbo is a hybrid TD05h T04E variant. Compression ratio has been confirmed. Base timing has been checked and confirmed. ECT is between 85 - 90 degrees C. Injectors (ID1000 and deadtimes have been set in the Link) have been checked and cleaned. Fueling isn't an issue. Running a DW300 in tank pump. IAT is between 23-26 degrees C Can't run anymore than 7-8 degrees of timing without it knocking especially in 4th gear. could this be a timing drift issue? Can't really get it back on the dyno easily to check timing with a timing light while its loaded up to see if it is drifting.

Its not the fact that i have changed to COP but that we've used extra outputs to change from wasted spark to sequential. We've run out of outputs for the tacho. Does the ecu hold power output need to be powered up or earthed for the ecu to power up? Cant get the ecu to power up to connect to a laptop. The fuel pump primes and theres 12v to the coils but theres only 3.4v going to the ecu and 3.4v at the injectors.

Hi there I am currently in the process of fitting a G4 EVO 1-3 plug and play ecu. We have an expansion loom fitted and are fitting additional sensors etc and have changed ignition from wasted spark to sequential as i am running coil on plug. The issue we have is having a tacho output so the factory tacho works as it would get its feed off the stock ignitor, but we dont have any outputs/inputs left other than ecu hold power. Will it cause an issue using this output? Or is there another way? Cheers
