The sort of attention to detail people look for in a tuer.

Here is my tune for my 2013 ZL1 with 1050x injectors, do a compare of the injector data, don't use the whole tune obviously 136459

99% that is a 2 step, not a tune. On GM ECMs you would need a separate two step controller.

Haha glad I could help, your results may vary, I can only confirm that the X-series gauges have the dual faced face plates, not sure about their other stuff.

Yeah in the scanner its easy, but he was talking about watching his wideband gauge in the car while driving and I think that's where he's getting thrown off.

I can't believe there are any scanners out there that won't offer a lambda reading/output but I could be mistaken, I know on the AEMs that not only can you switch it to lambda with a press of the...

A wideband sensors only measure lambda, i.e. how close the air fuel ratio is to stoich, it does not know what fuel you are running. Almost all widebands that show AFR are showing it on the gas...

I can't look at the tune right now. When cruising you should be at 14.7 in closed loop, to get the numbers you are getting either your tuner has forced the car into open loop at all times or...

Oh and there might be another box, I think it is called Wheel Speed Limit, this is another limiter that will work at speeds below like 15mph, as far as I can tell this limiter is always throttle body...

Go to Fuel > Cutoff, DFCO, in the RPM Limits column there should be a Control Methods section with a couple of drop downs to disable or enable Spark, Fuel cut or ETC. Disable ETC and Fuel and...

First off, I don't agree with the reason for doing this, I think it is for Honda Civics in high school but..... Many of the gen 4 and 5 rev limiters are set to use throttle body control, i.e. it...

If the manufacturer can't supply those numbers I would go with different injectors IMO. It is no fun to tune with bad injector data.

I looked through your logs and never saw fuel pressure, please log the Fuel Pressure PID, I bet the problem will show up clear as day, dropping during WOT. The cause does look a lot like it could be...

If you have fuel pressure then there are a couple of things that could cause you to be lean, due to all of the issues I am not going to assume everything is actually stock, these are all pretty...

When my ZL1 had low fuel pressure issues it was the fuel pump, car would run perfectly fine until WOT where it would drop to 30 psi and go lean. You need to replace the pump I am almost certain that...

Could try disabling the O2 sensors and forcing it to open loop, at least as a diagnostic. If the engine is stock it should run just fine open loop, if it runs well then you have a sensor issue, no...

Have you adjusted your ETC area scalar since swapping throttle bodies, if not start there, should help a lot if not solve the issues? Calculate the % change in area between your stock throttle body...

Well E85 is harder to start in the cold, it's why they add more gasoline the the mix in winter. Now the weather is colder the fueling has to be better and you are hitting parts of the starting fuel...

Closed loop can only target a lambda of 1.0 with narrowband sensors, if you are forcing it to go to closed loop early you are negating any of your cold start fueling which is normally far richer than...

My guess is set P/N rev limit to whatever he wants and then set rev limiter to ignition cut only. Should dump plenty unburnt fuel into the exhaust for what he wants. Then dump some fuel on the car...

I think he is very lucky that it is going into limp mode

Would MBT be knock limited at cruising conditions, I would think MBT would be best for fuel economy as it is where you are most efficient?

You need to fix your battery voltage issues first, injector flow rate varies by about 10% for every volt, that's almost a whole digit in AFR, if you have bad data on top of that big voltage issues...

Haha yeah, the thought process;

"I just paid $800 for a tune, that went badly, maybe a free tune from strangers on the internet with very little information about my car will go better"
