wiring an APEXi S-AFC to K8 V6 ECU

[EZ_4_FUN]

I've searched the ubb for related threads and no help so far. I'm having some serious issues with my frigin car now.

At first, it was all dandy and rosy, but today my idle shot up to 2000 rpm. It also stals as soon as you start the motor.

Has anyone installed this on the K8 ECU ??? I need some wiring/tuning tips please!

any help is appreciated.

Thanks

Ok. so after spending a few hours last night on it, I think I figured it out ( rpm wasnt registering).


Now, my car continues to rev very high ( 1500-2000). I disconected the battery over night to see if the ecu had learned some bad habbit, but its now the morning and it continues to do it.

Any Ideas please?

Thanks again

I have a ZE installed with the K8 ecu, but I had a DSM guy install my S-AFC. All he needed was the pinouts for the ECU. I can give them to you if it's any help.

If you still have them, perfect! I think i got it straightened out now, but its always nice to double check.

The S-AFC needs to be tuned properly cause im still running lean. I had my friend mess around with it tonight and got it goin pretty good. My idle also came down a bit after playing around with the tps.

It bogs out under hard acceleration at around 3000-4500 rpm. Is that because their is too much gas, or not enough? There must be at least 10 factors that contribute to this I presume...

Thanks for any help.

Well..

I don't have a S-AFC in my car, but from what I know, it's worthless with the V6 engine.

You can find a lot on info about the S-AFC here

From Jeff Abrams:

The KL PCM doesn't respond to VAF modification very well. This is why most S-AFC installations don't produce any results.
I used the Link AFM on my KL-DE and ended up setting it to zero and using other methods.

I am currently running an E-Manage on my RX-8. Works like a charm there, but the RX-8 has a hot-wire MAF, not a VAF.

The E-Manage can control ignition timing and directly ADD to injector pulse duty cycle. You would only be able to use the ignition timing control if you have an MSD or something similar.

I think it is possible to use the E-Manage with bigger injectors on the KL, but I can't say that it would produce satisfactory results in this capacity.
I would, however, use it to control extra injectors and adjust the stock injectors and ignition timing

Good luck

p.s. I don't understand why are you running a S-AFC in your engine...are you boosted?? Any mod??

[cris_barros]

Oops...

I figured out that it is in the FI section...so it's supposed to be boosted..sorry

[EZ_4_FUN]

Yes, its finally boosted.

Im running an IHI turbo from the older 2.2 probes on a KLZE. I installed a small side mounted intercooler; its in the area of the horn assembly.

Its currently set at its minimum which is prolly about 3-4 psi if that! Running like a charm. Not sure if the SAFC does anything other than look good

I finally got the idle under control, I was pretty upset and regretting the whole turbo project initially, but with a bit of patience, I must say it was all worth it in the end!

hey oscar got any pics of your set-up??..I'm interested in your piping route

Hey Oscar, James (we met @ Gabi's) So how is the turbo doing? LOL was @ gabi's shop when you called that night on the highway back to TO. Just before you called we were jokin about you calling needing a tow. What happened? And when you going to get some 1/4 times ??? Can't wait to hear how it does.

HAHA 1st gen MX6 turbos suck. Ive been messing with them for awhile now as i have a 1st gen mx6. Ive locked one turbo and just recently snapped the shaft on another, spun it too fast only pushing 12 psi! I cant believe it flows well enough for that KLZE! does topend seem to suffer?


I used a Grand national turbo for my KL03. DAMN is it huge. leans out pretty bad though on only 4 psi with a 12:1 FMU AND fuel pump. crazy stuff.


Cool nonetheless, at least you did a turbo install! any pics?
