    Use Lq9/ls2 or VAG Coils with Aem v1?

    Is it possible to run vag or ls2 coils with the Aem v1 ecu?

    Ask your mapper as he may have a preference.

    Mine fitted VAG ones. Tho he didn't even tell me there was an issue with my old ones until afterwards.

    Also, the cover will need to be modified as VAG coil packs are taller than OEM ones.

    Why are you changing the stock coils?

    Is it because the AEM v1 converts from direct fire to wasted spark, the old fix for this was a HKS ignition amp, I ran that setup on stock turbos and then again on a single up to 1.8bar using the stock coils.

    I have a Hks dli installed. The Problem is missfire above 1.5bar in higher gears 3-6. We tried new coils (oem denso and the red ones) with new plugs bkr8eix (gap 0.5) and bcp7r. All missfired. We tried coils and plugs from a 1xxx hp Supra running 2.2bar without any diffrence.

    Coilplug connectors are new ones. May I have to check the wirings from igniter to coils?

    If the 1xxx hp Supra is running OK with the same stuff, have you compared the coil settings between the two cars, it does make a difference.

    He isn‘t sure, since Aem 1 is a Longe Time ago.
    Je Said the vag coils and lq9 had to run waste and spark like the oem coils because the v1 ecu has only 5 ign Outputs...

    AEM v1 always runs wasted spark on 2JZGTE.
