First Data Log with the 13T's, Got questions. - 3000GT/Stealth International Message Center

Jasbo · 01-08-2008, 07:34 PM

ok useing my Hand Held Halo data logger, ive saved a session im hoping someone can look at with me and give an opinion...

The car is currently boosting 11-12 psi, and pulls pretty hard till the rpms get up to where I feel some hesitation and the car stops pulling. I eventually let off the gas so not to prolong the symptom.

Im not getting any knock, Timing looks a little funny, and O2's are pegged... Im thinking im looking at a flooded condition being my IDC's are hitting 90% around 5400 rpm but id like someone else to take a look at this with me...

Anyone out there able to look at a HHH session? I can e-mail it over of course.

Not even looking at the log, if your running 550cc injectors at base fuel pressure (43.5psi) & hitting 90% IDC at 11-12psi, then your running too rich.

What I do is shoot for .92-.96 nb o2's while watching for knock (I only "tune" with 4 knobs so it doesn't take long).

I would go for .88v-.92v unless you are getting excessive knock then go for .94v. My old WB02 was showing pig rich .94v or above.

You sure you don't have a boost leak?

pretty sure... Thought of that and checked all my hoses, but everything is tight. My O2's were pegged at 1.01v so im pretty sure its just flooding out...

What is your SAFC set at?

Hannibalzero · 01-09-2008, 04:56 AM

I agree that 90% IDC sounds high given the injectors and the boost pressure that you are running. 1.01v is running pig rich. I'd say start trimming back fuel until you hit about .92v, then slowly fine tune it down a little bit further until you start to see knock.

Jason, you can email it to me if you'd like. I won't be able to look at the session until I get home later tonight.

Its very easy to have a boost leak even with tight hoses.

Might also want to swap out the Apexi Neo as our cars have issues with it for some reason.
