As the title says, I'm having trouble getting the car started. I just put together a DIYPNP with sequential fuel. Car is a 97 with 330cc injectors, maf is still in place for the moment. I have 550s on the way back from Deatschwerks, but I'm going to hold off on them until I can make some progress with the current setup. I the settings off DIYAutotune's site for ignition and set up the Engine Constants properly.
I spent quite a while playing around with the ASE percentage and cycle settings, as well as the cranking pw settings, which are in a percentage (Cranking Pulsewidth% is what TunerStudio calls it). The best I got was every few cranks the car would start up, rev to about 1300, and then promptly die. Since TunerStudio is putting pulsewidth in % instead of ms, I can't just copy someone else's settings as a starting point, so I'm not sure where to go on that. I basically started at 0 and worked my way up until the car would sometimes start (and then die right away) before giving up.
Part of my Cranking PW (it's 90F ambient here):
Coolant (F) | Cranking PW%
61 | 300
88 | 280
109 | 260
130 | 200
I'm also pretty unsure where to go with my ASE settings because I can't tell a difference with the car dying right away.
I also have a short datalog of 4 cranks, the last where it rev'd and then died:
I'd like to think the issue lies in the settings and not elsewhere because every once in a while the engine actually does fire up and sound like a normal start.
Appreciate the help.
Edit: I should also mention that my VE table is sorta made up based on what I got from the old .VEX generator on msextra.com, and the spark table I found on a thread here (5 or 6 members said they ran it).
