what nozzle are you running?

 

5gpm. Im thinking either my plugs or the nozzle. Im going to pull both tomorrow. Any other thoughts?

 

Well bogging is due to getting super rich. When you were tuned for it it felt strong?

I advise you not to hit meth anymore. If you wash your rings enough you will need some new ones.

 

5gph is what I run, wht psi is the meth coming on at? Progressive controller? Check the plugs, it wasn't doing this in tuning?

also did you **** up your mix? Chris knows how exact I am about my 75/25 mix lol

 

The only way I can remotely see him ******* the mix up is if he was tuned on 30/70 and put in 70/30. Def. check the plug gaps, maybe getting washed. Also compression may be putting them out mine did that once. Ran like absolute **** when that happened.

Does your AFR gauge go below 10.0? Or is that it. It could be going more rich than 10.0

 

prolly doesn't read below 10 but I think I saw where he was running 50/50 maybe he forgot to mix it? Lol I doubt it tho

 

Felt extremely strong when Steve tuned it last June. He put 25* of timing into it with no knock.

 

When I mix I use a measuring bottle everytime I fill my tank.

Was tuned running 75 meth/25 water. AFR gauge does not go below 10.0. I bought new plugs earlier today and have not installed them yet ( NGK 1 step colder). What gap do you recommend?

 

check the plugs the nozzle isn't going to allow more than 5gph, sounds like an ignition problem

.032 for gap

 

Have always ran 75/25 since I was tuned last June lol.

My first thought was the spark is being blown out.


Progressive controller. 5 on 12 full.

 

you have the exact same meth setup as me as far as mix and controller settings lol

you are definitely blowing spark, any codes?

 

Aeroforce are clean. No codes. I think its a lock that its the plugs. Im going to pull them tomorrow morning and post pictures of the bastards. Thanks for all the help.

 

Emailed you the new sig steve. I LOVE your car!

 

Haha, looks like someone punched your cobalt in the eye.

Hope to see people at the pavs again this weekend!

 

by one of those damn srt4s! lol i wont be out this weekend maybe next week

 

Can someone test the supply voltage of their CKP sensor for me please? The car needs to be in the on position. I have it narrowed down and and stuck because IDK if there is supposed to be voltage or not.

I texted someone to do it but they didnt have a multimeter.. not going to name names.

Pics of sensor location and harness here.

Thanks. My wheels are are Drag DR 34's 18x8. I changed the plugs. The old ones were burnt up and the gaps were out. The car doesnt bog as bad but its still rich as hell. Ideas anyone?

 

Its still rich? You gapped to .032 right? It seems you are not reducing fuel when meth kicks in. Are you sure your controller didnt change settings? Have you still tried taking it WOT to RL? If so does the power come back?

FYI your sig doesnt work.

 

Still rich. gapped to .032. I have taken it WOT but not to RL. Controller is still at 5/12. Think it has something to do with the fuel learn? You saying that beating on it will relearn and correct the issue?

 

No I was seeing if possibly just getting too much fuel in the beginning when the meth kicks in but leans back out top end.
Is it still pegging 10.0?

 

I am going to go try a RL run.

 

Just be careful. I wasnt exactly saying do it. I was just wondering if you have before. If you are running extremely rich too long you are going to have some issues. You dont want to wash your rings.

If you noticed that your power came back top end or the AFR goes back toward 11.5 then there is something wrong with the tune (pe, maf) or your controller I would think.

You dont have any codes?

 

Its cool. I keep second guessing the power. I know for a fact it feels better with the new plugs but I dont think its 100 percent where it should be. It was still 10.0 at RL. Keep in mind I just installed the wideband a week ago... so I dont know where my AFR was at before. I trust that Steve's tune last year would run between 11-12.0 WOT. Steve told me to get a wideband before he would re-tune for my 60's and 2.7 which are sitting in my garage stairing at me every day. I need a new tune but Steve seems to be very busy lately...No codes either...
