what "electrical gremlins" were "sorted out" before the tune?. using onboard map sensor in the ecu, or an external one? doyou have the full injector dead time figures (8-16v)? if not SET THEM TO ZERO. remove injector resistor. set injectors in the main set up table to the propper setting.(drop down menu explaines)
was it tuned throttle over map,afm,or just map? ve or injection time? set coolant temp correction to zero and warm up. (all this will have to be done at the dyno)
injector latency is not nessesary, all it does is add a time to each event. if it is not set correctly the thing wont evan start. (had the same issue at work with id1000's. there values were heaps differant to the default haltech ones. changed them and started first kick.
so if you dont have the exact documentation on the values, set it to zero as it will make tuning and cold starts uber hard with the varing crank voltage.
