power cuts off and idle is inconsistent
12 psi. 650cc.. the unichip crappying out? help.
thinking F-Con pro, but not positive it'll fix the problem.
gonna have it looked at next week.

 

does the unichip pull timing if it sensing knock? it could be that if the unichip does that.

 

it should..

 

Mine is still doing this also. I have the UTEC.. so it may not be the computers fault. Someone said cleaning the camshaft sensor got rid of their hiccup and rough idle. I haven't tried it yet, but I'm throwing a code for the crank sensor?

 

is this the new car you bought?

 

First of all, unless the stock ECU was reflashed for the larger injectors, there's no way that Unichip can deal with 650's.

Find the nearest FCON tuner and get the works, you'll never look back and it'll be the best 3-4k you ever spent

 

yeah, picked it up yesterday

If I know for sure that's the issue, I'd have no problem doing so.

 

You wouldnt happen to be getting a p0011 code would you ? I have had this code since build and it justwont go away !!!

 

have fun with the car paul, i know you'll completely fall in love with it as soon as you get the f-can, it was great meeting you and i'm happy that you got home safely.

Not really true ,the larger injectors are scaled down via MAF voltage manipulation.
Note the base APS TT kit ,comes with a Unichip and 550cc injectors , no reflash and and idle is good. However; the Unichip + MAF scaleing still does a crappy job of scaleing down even larger 650s. It does, but it just provides unstable and sluggish fuel mapping. One symptom of power cut (hesitation) under a heavy load transition is caused by the rapid swing of the 1:1 RR Fuel regulator (analog Boost controlled), that the Unichip can 't scale out. So upon slamming the throttle down, you can go very rich for a brief interval , which causes an annoying stumble.

 

Actually the APS TT kit comes with self-proclaimed 500cc's, not 550's, but under the industry standard psi, they only come out to about 440cc's.

I had the exact same setup that Cannysage has....APS TT and 650's, but I had the AAM fuel system. Tuan at GRD could not get it to run right without the reflash.

 

"Nismo Floormats"

Yeah, that's what i told a carrera S too..till i blew his doors doors off...

 

Yes , right 500CC at the non srandard PSI. Either way they are scaled down, albeit with a lame technique.

I am currently running DW 650cc injectors with the Unichip, built block, S1 cams, CJ return system, 3.5 TPs , 3inch TD, "no" re-flash on 91.

Idle quality is "fair" once warm. However; it is nearly impossible to lean out the 1:1 Fuel regulator transiton with the Unichip. The UniChip + MAF loop is just too sluggish to keep up with very rapid boost rise I get. I transiton from 0-12.5 psi from 2k-3200rpm. The Fueling issue may also be one symptom being seen by others?

I am debateing FCON, AEM or even Hydra. The Unichip is a temp solution and the UTEC (it was tried already) pretty much sucked IMO.

 

I remember even with my reflash, idle still sucked for some reason. Really jumpy. It was chalked up to my JWT cams.

When I got the FCON installed and tuned, I was AMAZED by how well it ran out of boost, and idled. Like stock, even with my cams. If I were you G3po, I'd get the FCON, but I'm biased because I had it.

is this BigBri's car being whored around?

 

No, I think it was Marluci7's. Same difference though lol.

 

^ Wrong car. I have nismo floormats.

 

Oh, that's right, I think Marin only had stock mats.
