Whats up guys, i followed the TT ecu mod writeup while retaining the oem dizzy (No COP) using the DS62 ignitor etc etc. If i plug in an oem ecu the car will run, however if i plug in my AEM v2 with a known working map the car just cranks and wont turn over. AEMtuner is showing low crank signal and im also getting weak/no spark. Do i need to swap back to my OEM ignitor? Load an N/A map? im ot sure what to do and im stuck. I also dont have the OEM ecu anymore so i cant even trouble shoot
