There different gauges completely. You can see on the AEM gauge that the left side reads 11 then goes up to 16. So It goes from rich to lean in the clockwise direction.

I am assuming this is with meth and the higher boost? I dont think its the dwell as it is a smart igniter and the stinger has no control over dwell. I would just play with your tune and plug gap.

You have been misinformed as lean is to the right. BTW you should go by the actual AFR and not by which direction the gauge goes. Either way most gauges start from the the lowest value and then go up. So it would start rich and then go lean. Also why would they make "green" the danger zone...

Green is good my friend. The left is rich and the right is lean.

Code 31 is your air flow meter signal. Have you checked to make sure your map sensor is correctly plugged in?

Well for starters 11's is running rich and when in boost that is completely normal. Have you done a full pull and looked at your AFR's? Also the purple injectors are 550cc injectors.

Send it to Driftmotion and they can repair it confidently.

Jay I don't get a miss with my enrichment that low but every setup is different right? I would say you are running a tad bit rich and might be getting rich misfire. Try to aim for 11's with meth and it should be fine.

I use a 50/50 mix by volume as it is not flammable as well.

Well would the stock 1J/2J ignitor be considered "smart" then?

Also Jay make sure you arent running too rich either because I know you can get rich misfire as well.

I thought it was mentioned that the Stinger does not directly control the amount of dwell but rather the igniter does? I may be wrong on this matter but I thought someone mentioned that at one point? 1jz, 1.5jz, 2jz: 1jz Turbo size: Apexi IHI C7 (66mm) Exhaust housing: Neverchecked Dwell...

^^^ Isn't the truth.

Did you bother checking for codes? I would start there first and see what it says. I am going to go with the ecu just took a dump on you though.

I agree hopefully you can get that sorted out.

Maybe I should start looking into a ball bearing turbo. 10psi by 3500 rpm is a lot nicer than 4100.

You should have no problem with detonation at 10 psi. I am running around 23-24 degrees of timing at 10 psi on 91 pump gas and have zero signs of detonation. I thought my tune was conservative but I guess not hahah.

It might not be your wastegate that is causing creep. Normally it is due to a poor manifold design and not the wastegate itself. If you have a fair size wastegate (40+mm) then it should easily be able to support your turbo and power mods. Mine tends to creep about 3psi as I go to 7k so it is a...

Well I am glad you finally have it narrowed down now.

You need to remember that the current drawn by the fan is much more than the Stinger will allow. I think each output is 1.5amps or something. So you need to wire in a relay to make this work. Something like this will work. -Pin 30 (30 amp inline fuse) to Battery -Pin 87 to fan power side -Pin...
