Thread: Next Mod and KR reduction Ideas

Yes I have read the stickies.

Here is a list of my current mods.

- Wizaird CAI
- Ported TB W/spacer and sheild
- ZZP coils and wires w/ 104 iridiums Gapped at .055"
- 160 stat
- ZZP tune
- Front and rear plog w/ ceramic crossover
- 3" offroad downpipe
- 2.5" SLP cat-back

New fuel filter and fluids throughout.

I am still getting upwards of 6*KR at times with my 3.6", and 3-4* KR with my 3.8".

What do you guys think? Is this ordinary?

I am thinking i should have just gotten headers instead...

My KR was the same before I put the ZZP coils and wires on.

I do have an aero force scan gauge, that's how I'm reading my KR values.

I am running the stock thermostat for the winter months. The 160 is ran in the summer.

I may try a dyno tune in the spring.

With the mods I have shouldn't I be able to at least run a 3.6" ??

apparently not

So Red crap suggested a dyno tune. Thank you!

Any other ideas? I was thinking yella Terra 1.9rr or ZZP headers.

Thanks Fivefinger for the TB idea. Of course I shipped my stock one back for the core.

I see your in Rogers, I work in Rogers. Good to meet a local person. If I was going to do a dyno tune I was thinking about DB performance. I've had my old LT1 on there dyno for a numbers run.

I don't necessarily want to pay for a dyno tune yet with basic mods. what could I bolt on to potentially reduce some knock? Rockers maybe...

I would throw a set of rockers on and see what happens. Worse case you drop a few degrees on KR and pick up a few ponies. It could clear up all the knock.

I was thinking rockers as well. I'm going with the YT 1.9RR and LS6 springs.

What else should I replace while the valve covers are off? Valve guide seals? Etc... 92xxxmi

I was thinking lifters but do I have to take off the SC and intake manifold?

Thanks
Zach

If you put a ported TB on and don't calibrate the PCM, it will run lean, and it will have KR.

I listed all my modifications for ZZP when the computer was tuned by them. I would hope they would take that into consideration. It wouldn't suprise me if they didn't.

What parameters on my aeroforce scan gauge should I be checking for timing and A/F ratios? Or anything else that could cause my KR?

Thank you for the feedback!

the aeroforce will display commanded air fuel ratio, but not actual. you need a wideband to see the actual AFR. you can also tell the aeroforce to monitor O2 sensor readings, but it is difficult to see because of the huge variance in numbers, and when it is important to see, you are at full throttle looking at the road. if you can set it up right, you can record the parameters with the aeroforce while driving in wot. it will record about 30 seconds. at full throttle your O2 sensor should read about 930

I've seen where ZZP's throttle bodies skew the MAF values by as much as +15 on the LTFT's. Depending on what stage, the throttle blade doesn't even seal against the bore correctly.

I am finding a local used throttle body I will change it out this weekend hopefully and update you guys with my KR problem.

MeanGrn99GTP I ran a 3.6 setup on a gen v on my 04 with 1.84 yt rr stock springs, sd headers, 104s, and 180° thermostat.

If u would like I have DHP power tuner and I run to the cities alot if u want I can either set up up with my old 3.6 tune or I can run some custom tuning for u
