SCT/ mail order tune problem

fastregalwe2 · May 22nd, 2009, 07:47 PM

I have an 08 Saleen that came s/c'ed. I just installed a 3.4 pulley, HT0 plugs, and my email tune from JDM. Took the car out for a drive and as soon as it hit boost it was spark knocking BAD. I am using the SCTx3, what can I do until I can get back ahold of them on Tuesday, besides not driving the car and/or not boosting it. I went into the Tune Car option and the only change I can make to the JDM tune is axle ratio and tire size. I can go to the Custom Tune and change stuff but its not the JDM tune. In that option though the 93 octane was checked and its supposed to be a 91 octane tune. Dunno if that even has anything to do with the JDM tune or not.

Do you have any Gauges to see what's going on, also did you upgrade you upgrade your fuel system?
which injectors are you using?

Hmm ... what did you gap the plugs to?

Jim at JDM said I would be fine with no fuel upgrade. My car came with the 39lb inj, its the 465 hp rated car. The plugs a paid the extra to have them gapped at .030

I did order a BAP on Wed though as an added insurance policy. But, I was told it was not needed with the 3.4

No gauges, just the monitor on the SCT, glanced at idle/low rpm looked like 17* timing but I'd have to see if the data log saved in the SCT

Try to get a Datalog and send them a copy so they could se what's going on.

In the meantime I wouldn't get into boost.

the log shows 15-18* timing. Supposed to be a 91 tune

Jim got it straightened out today. He pulled 2* timing out of the tune putting me at 16* base.

How does it drive now

fastregalwe2 · May 23rd, 2009, 10:33 PM

much better, but I dont like not having the extra timing. I saved both tunes. I will load the 18* one after the BAP and vac line kit gets here Tues and see if that will allow me to run the 18* instead of the 16*
