Yes, I searched charlie2020's posts and since I'm running a stock BlueBird DET ECU, I have my S-AFC setup as

02in - 06out.

I'm getting proper readings (so it seems) via the maf. I've checked for boostleaks 1000 times.

Heres the problem, as soon as I see a few psi of boost, the car falls on its face. I would instantly presume boostleak, but I've checked a million times with a pressure tester.

I had a similar issue not too long ago, and when I swap'd from an MSD ignition coil back to the stock ignition coil the problem went away.

Heres the odd part, I played with the AFC, and if I set the S-AFC to 4/5/6 in-6out It'd rev fine hitting 7-10psi of boost (?)

I'm completly lost in what to check. I guess I'll try to find another ignition coil to verify its not that crapping out again.

Why would it run fine using 4/5/6in-6out but not 02in-06 out?

Sounds like timing. does it detonate when it boosts?

as far as I can tell, no detonation, never had an issue with it detonating before

What fuel pump and pressure?

John

walbro 255 highpressure pump, it seems as *** the fuel pressure w/ the vac. disconnected is ~50psi, although it should be at 3bar, this is the fuel pressure the car was tuned with, so I know its not running rich.

bootleaks are also 100% out of question, as I threw the TMIC back on, and pressure tested it. Gonna swap the SE-R maf back on to see if thats it.

What are the chances that I could possibly have crap'd out another ignition coil?

When it falls on its face are u able to monitor o2 voltage to see if it's lean or to rich?

Heres that link to MAF numbers for anyone that never seen the list:

I swap'd the stock SE-R maf back on, and changed the AFC numbers back to 6in/6out and its still crapping out. I pulled the plugs and they're really rich. I'm gonna slowly lean it out a little with the AFC, see what that does for me.

Arr... took a look at my S-AFC fuel points, and somehow the thing managed to be set at +28 from 3000 up, not sure how that happened. Just happy it wasn't -28 accross the board :eek: Well now I get to reinstall the FMIC and Z maf, fun (bleh)

Thanks!

why does it always have to be something stupid and easy

Charlie2020: Should you have to re-tune your fuel points/curve when you swap to the Z32 maf? I got the car running good with the stock SE-R Maf at the fuel points that It was dyno tuned with. Then I swap'd on the Z32 maf and it ran really rich. In order to get the car to not flood itself, I went from +22% to ~+6%

Thanks!

the z32 mafs shouldnt change the fuel mixture unless you were maxed out on the stock mafs and now this one would flow the correct air.. I think in that case though you would run leaner not richer(but I may be wrong). My maf change did not effect the fuel mixture.

hrm I was right at the 230fwhp mark, I think I'll throw on the s3 cams and FPR and get it re-tuned asap, gimp it down to the shop
