Repost from my other thread. Put it in wrong one sorry guys...

Well we tested the setup out on the weekend, running at a local street drag meet, wasnt much traction but still run consistant 95mph and worked perfectly all day.
So next step, nitrous control :driving:
How would one go about setting up a time based table and about pulling timing with the 11p? Im thinking map switch or shorting map out, but unsure about time based table

are you still spark only?
on the 350 chev I did, he bought one of these. Instant EFI, delco loom plugged directly into TPS, IAC, Injectors.
not as good as multi point... but was way nicer to tune than the carby.

yep still spark only at this point, would like to go to multipoint injection down the track. they are pretty good things but very expensive aren't they? trying to keep the budget intact so most stuff is recycled lol.
yeah im handy with the carbs but its very time consuming trying to get every part of throttle sorted, currently got a lean spot on part throttle, cant cover it with powervalves so its a bit rich all over to compensate :wall: seeing low/mid 12 on wot

so fitted a set of resistor plugs, can log for a minute or two occasionally now :comp:
got a few logs, ross 3 has 2 runs from drags, made some jetting changes (there's a long no data bit in middle).
the other one is street driving a few days earlier

are you using an aldl cable connected to the obd2 socket? I was tuning a v6 conversion into an escort recently and we had major comms issues. turns out the earth for the aldl socket had been run to the car body. spliced the aldl earth into one of the PCM earths and comms issues gone. just an idea.
