  2. Intermittent trigger issues

    in G4+

    You will need a cam sensor for direct spark ignition.  With no cam sensor the ecu has no idea whether it is TDC compression stroke or TDC exhaust stroke so will get it wrong approx 50% of start attempts.  

    If the other car with no cam sensor started reliably then it must have been using wasted spark ignition - but your injection timing would have been randomly incorrect in that case too.  

    You know what Adam you are bang on, that’s the only thing I’ve overlooked here and yes the other cars have been wasted spark, excellent thanks for the input

    Morning 

    We have an Evo 8 with a thunder running 18-1 trigger, base timing set at 110 and runs fine no issues when it runs, drives fine, however even when warm theirs a 1 in 3 chance it wont start again and trigger error counter rises, new sensors crank sensor, wiring checked, cam sensor is disabled, is it still looking for something ? Weve based this trigger setup of another car i had with no cam position that worked fine and started every time, thanks

  6. Moving ECU hold power

    in G4+

    Thanks for the input gents very much appreciated, I thought this would be the case and was very optimistic about what I could fit on. I think maybe going to a wire in ecu here as I’m requiring dbw, 8 injectors, sequential ignition, flex fuel, oil pressure, oil temp. So that alone I’ll need 2 extra ign channels as well…

    trying to free up injector drive 5678 for extra 4 injectors, moving ecu hold power from injector drive 8 to ignition drive 3, pin swapped pin 38 main relay into pin 22 ac, were on the money with wiring but doesnt work, can ignition drive 3 not be used as ecu hold power? even though we can select it? evo 7 4 plug btw

    running dbw on expansions so limited options

    thanks

  10. Stock evo 6 non start

    as per title, nothing weird and wonderful, stock evo 6 bar fully forged, runs fine on stock ecu no problems. Wont even fire on a base map, maybe coughs now and then, then floods engine within a few cranks, engine speed signal looks weird but runs fine on stock ecu? 7 bar map sensor defined on this base, tried different trigger options but nothing. input welcome.

    also tried 0 cold start and switching off as my corrections as possible still non start

  11. Laptops constantly freezing on WOT pulls

    in G4x

    Posted

    Ok so all Evos 5-9 so far, at first it did do the freeze then re connect, but it seems to have got worse, where as now it locks up the laptop, the bizzarre thing is its on all 3 laptops....now i used br8es plugs which are resisted, and leads are oem, igintion suppressors ive not took much notice on as i do know people like to get rid of those. Another bizzare thing is that is fine on certain roads and horrendous on others......never had a issue with the g4+ doing this, same conditions?

  17. CAN bridge failed - check ecu firmware

    It’s not plugged into can2 it’s in can1 at moment , had to upload low res as the file limit size 

    basically the multimeter is showing 12v power to the can lambda red/black wires

    can green/yellow is showing 60ohms so can line is good also 

    Also pinned into the back of the can plug to board reading 60 ohms still everything plugged back in

    have you tested it with the engine running? The CAN Lambda doesn't start the sensor up until after the engine is running. It is also possible to send it CAN messages to make it run while the engine is off.

    Yes always with engine running mate

    Please attach a log, the tune, and some photos of how the lambda is connected to the ecu.

    Ok mate will do today

    But I’m using the find devices to see if the ecu can see the can lambda not to reprogram it, just as a test and I can’t even press find devices as it’s greyed out and says the above message. The can lambda has 12v to it can line has 60 ohms on it and I’ve tried reconfigure the can lambda to communicate on can2 but it’s find devices is greyed out and all I’m seeing is said message....
