Microsquirt running - but with incorrect VE/injector data
Hey all, I just recently got a 12A Turbo setup going using the stock turbo and intake. Swapped a 12a center iron for a GSLSE iron, and added some ID 1000 injectors to the primary rail. batch fire injectors, wasted spark FC coils...I'm pretty familiar with the squirt as i've run it on my 13BT and also 20B now.
I got it to start up if i doubled the VE values, or if i set them back to aaron cake's base map and set my injector dead times to double their value (1.1ms per ID, runs well with 2.2ms) but its sitting here smoking out the exhaust reallly bad. its definitely fuel, not oil or coolant.
So far I've verified I have 43 psi fuel pressure engine off. roughly 37 psi while running
timing is correct.
fueling and general settings all match the MS2 options in per aaron cake guide.
verified fuel going into the fuel rail is on the correct side.
only things i can think of is a damn vacuum leak...but it didnt show up with a smoke tester.
what confuses me is I have the little follower dot on the VE map but not the ignition map. its got me wondering if there is a setting somewhere I missed.
A bit of a ramble, sorry its been a long day...I can post a video tomorrow if that would be more helpful.
