diypnp sequential
 

i upgraded my diypnp with the sequiential module, car is a stock 94. car ran beautifully on batch fire. it is wired as found online NJ output #1 - 4U , INJ output #2 - 4Y, INJ output #3 - 4Z, INJ output #4 - 4V. settings in tunerstudio set to sequential with additional drivers as stated on the site. its pig rich in the log, pulling fuel makes it shut off. any ideas would be helpful,
thanks

and you setup your drivers like this?

Do you have PT6 or PT7 in use by anything else?

The drivers are setup like that and I had pt6 used previously to install but shut it off when I added the sequiential board.

Also last night I brought it inside and used output test mode and my multimeter to make sure all the injector channels actually output a signal and they do. So not sure what's screwy

Should it be at 1 squirt per engine cycle? I imagine that it's having trouble injecting such a small amount of fuel with 4 440cc injectors.

im on stock 254cc injectors but I didn't think about the squirt per engine cycle I will check that. Even though the sequiential tune should have that set in theory.

you can set it however you want, but it's always going to do (1)

one squirt is easier for a larger injector than (2) short ones...

heres with the correction to the squirt per cycle didnt really seem to make much of a difference.

and you've confirmed with output test mode all four are working, and on the correct cylinder?

the way you wired it sounds correct, but always nice to double check.

should be
INJ A-Cly 1
INJ B-Cly 3
INJ C-Cly 4
INJ D-Cly 2

output test mode triggers continuity to ground when pulsing.

do it on car, just make sure the pump isn't running.

thanks for the help brain, but i had to revert it back to batch fire for a little while. my mustang decided the bottom end was no longer suited for life. ill probably revisit this in a week or so.
