MS-II idles/revs poorly...no driving right now

Post by ion_four »

Hey all. I've persevered with this for a good 6 months now...I had the car running really pretty well back in the early fall, but something went screwy with my distributor (though I didn't know it at the time) and after fooling with the car, forever, I can't seem to get it back to where it was.

The engine is a Toyota 20r (2.2l) SOHC with (what I believe is) a street cam, intake, header and exhaust and 320cc injectors. After tweaking my ReqFuel a bit, it's gotten better...but I just can't seem to get it to idle well and think I'll get screwed at emissions testing.

Can someone look at my file and see if they see anything retarded? I haven't tried to tune anything, besides idle ~800-1200, so I know the rest is way off...HELP :)

Actually, it's just my MS file, not a data log...I believe MS2.2. Though, 297 bytes is way too small...something is wrong. Grr.



Basically, I've got a 2.2L engine, 320cc injectors and my ReqFuel is 11.0...does this sound alright? At 800rpm idle my PW is about 2.1ms. with ~25-30% efficiency @30-40bin, as I recall.


I'm at work now, so I won't be able to do any loggin' until this evening. I will update then.

req fuel of 11 sound reasonable to me and map of 30-40 is also very good.

I have a 4 cylinder 2.3 with 270cc injectors and I run at 13.0 req fuel.
My VE at idle is rather higher though at 40% but this can vary a lot between engines.

OK, here should be the real msq file...I don't know why the last didn't post. Sorry it's been so long, I've been busy with work.

I'll try to get a data log later tonight, or tomorrow, when I get my wideband recalibrated.

Thanks!
