heres a culmination of my 2 posts on another board:

Ok ive sent the ECU back to haltech and they diagnose it as good. So heres the problem:



normal driving without boost drives fine, no hesitation or anything. soon as i hit boost (which doesnt take much with the .81 hotside of the t74 turbo) it starts to frag up and fall apart occasionally catching back up with itself.



does this seem like a map sensor (try a different nipple maybe) issue?

perhaps the boost portion of the map is still way too rich?



when it breaks up it smells like gas like if the ignition stopped firing but the injectors didnt.. maybe a bad battery to chassis ground?

well i added a ground from battery to block, no help there. this is irritating. if i do a datalog of what its doing think anyone can disect the problem?

nope, tach is solid oddly enuff. my other question is my crank angle and tooth offset are 78/3 respectively.. what would it be at say 5 or 11 to lower the # from 78? i heard awhile back that sometimes the haltechs have an issue when the trigger angle and timing are above a certain number problems arise.. but like i said, when i get higher up in the RPMS (less timing) it cleans up and doesnt do it as bad.. so to me this is sounding like a timing/ignition problem?

it could be a tuning issue, do you have really big secondaries? it could also be way lean too. or maybe the secondries dont work at all?

850cc primaries w/ 1680 secondaries.



i know the secondaries work since i was using them for my primaries. when i initially installed the engine it had a 1 rotoring problem which ended up being a bad brand new 850cc injector so while it was out being fixed i ran it off the secondary injectors

hmm ok so you're not running staged injection at all?

no theyre staged, but i was just explaining how i know the secondaries are good. the car WREAKS of raw gas when i hit boost so im wondering if the fuel isnt atomizing or something when the secondaries kick on

maybe its too rich? ive had that happen before, you can have it rich enough that it just stops running/falls on its face.



try leaning out the first couple of bars under boost, see if it gets better or what
