Thats sorta the process I have been using, but didnt know if interpolate the whole or verticle/horizontal. Didnt know if there is a STD practice of...

Is that due to low battery voltage or a wiring fault for the OBD 2 connector? You should be able to get a log of it cranking if all systems are...

Holy crap, you're right. I didn't notice that it went over 100% like that. That's one of the first times I've gone that high in the RPM and hit the...

Ivt terms?

your timing hihg an low dont match your VE table is amazing, im surprised the engine runs at all your Pe timing and delays big i didnt look...

This engine has a mechanical issue. This is noted by the MAP at idle for starters. In the heading of your post you mentioned something is tired, is...

start off by telling us what you have. cam injectors fuel supply exhaust engine and engine parts

As far as I know all Polaris MG1 require an unlock.

Log cam sensor counts and watch it while you are cranking. If it stays at 0, try swapping the OUTSIDE two wires on the plug. I had that happen to...

MAP is inferred in mustangs.

You can use the Interpolate data function, then smooth between boundaries or hand enter based on the trends on either side of the cells you are...

JT, I figured it would be the same in principle. A wise man would prob do just that, I think Im gonna throw some parts at it and see. It would be...

Gt Storey:...

I think your correct the sensor is not required for the Mustang it just uses "MAP" values in certain tables. sorry for the confusion.

Looks to me like your either out of injector or out of fuel supply. INJ. duty cycle does go above 100 percent more than once in the log and AFR goes...

I thought that too but have filled up at 2 different gas stations and tried adding a couple gallons of E85 but didn?t help

Thanks Smithspeed. If I?m looking at your link correctly it references F150 which I know they use MAP sensors for actually manifold pressure. I know...

Those injectors you have in this one are OEM from a reputable source correct? And you have verified fuel pressure right?

You need to log the PID for drive mode/pedal mode to determine what is A, B and C. The labels in HPTuners are incorrect for these tables. Example,...

I'll compare it to my L87 cause when I took 5 degrees out almost all knock went away and I get 92 octane. Maybe bad gas?

Got ya. I have noticed that at WOT it's steadier like your saying. Thanks

I agree with making him fix it but it will sit until he’s ready or can make time. He’s flashed it 3 times with no success in fixing the cold start. I...

I'll do my best. Just to be clear, this is meant as an addendum/clarification to the groundwork that was already done on this topic, not an effort to...

What is "intake air flow restriction removal mod". Is this initial startup on the truck or a change on a running truck?

Evans would be a good option for you. The Tuning School is also a good option. I've done both and I don't think Evans covers 4.6 specifically, they...

That's what I've been told... I'd love to have a real blower on it but it'll do for now.
