i got got an L83 Engine V8 on GMC Sierra , I already swap the trans to TH400 and I wanted to switch one time to stand alone , for those engines i wana cancel the direct injection ( block it ) and run an intake manifold with port injections , is the trigger setting like an LS1 engine ? The cam phasing is limited already
Sorry I have no idea as I've never dealt with the L83. Chances are that even if there is no current trigger mode for the M1 ECU, MoTeC will be able to develop one given an input capture from the engine.
