Well done for stock cams!!!!! cant wait to see the future mods!

[Onemanshow]

NICE JOB i must say you went from stock XER to the stock Z20LET power , nice , more torque might be a future work on progress plan , but very nice .

[CostasGR]

Hi Johny, nice project, this power came from stock map ecu???, it's weird! I'm building x20xev with some goodies, like XER cams, exhaust manifold etc but I'll go to Megasquirt way, the stock ecu doesn't seem to has futures to run those cams. Maybe I put some throttle bodies to see power like yours!

anyway, I like your project, keep tuning

[Johny_X20XER]

The siemens simtec 70 ecu from x20xev / xer. can easily upgrade the map ... no problem!

you need to install the program from xer and then adjust the settings on your engine
