26 gt A10 3.15 gear, pump e85. Ess g3 kit with full exhaust. Full weight with 275 pound driver, weighs 4100 pounds as tested. What I added since my last post. 110 pulley, showing 12.5 psi at 7750rpm. Gt350 pump basket with gt500 pumps. Lawn racing dual fpdm wiring harness, radium inline fuel...

I put s550 quad tip corsa on my s650.

It does have 2 pressure sensors however the other one is basically for the DI system. Around December of 2025 ford switched to the cheaper 3 wire ecoboost rail sensor it uses a different sealing surface as well. It basically stays inferred around 158* to 161*. Previous to that is was actual fuel...

Does your 26 have the 3 wire fuel pressure sensor? if so then temp is inferred you'll see it mostly hanging out at 160* if so. On the factory cal hard limit a little over 10ms is all you get unfortunately. Pcmtec has a parameter that will allow it to go a little past 12ms if needed but after...

Some of the issue you were seeing with your ESS car was the factory fuel rails they are horribly restrictive, it causes massive pressure drops. The roush and whipple cars obviously don't have that issue with the rails. The factory s650 fuel pump is pretty impressive I felt, maybe you had a weak...

I like to rescale the entire feed forward table when using a bap and the minimum like you mentioned, even the autostart minimum voltage when equipped. Another option is to raise the max voltage to 15 volts, adjust the feed forward tables accordingly then command that voltage from the alternator...

If you're going for 800 rwhp on e85 you'll want some sort of fuel system.

Fuel-it makes a Bluetooth inline ethanol sensor kit.

Yeah AI is funny. This gen mustang still has the 16 gallon tank.

Coming from the bmw world as well with so many DI failures I prefer to have a little less ethanol content. We use to run upper cylinder lubes in the gas to help with DI lubrication on those.

The difference there is DA. Over 800 difference is substantial on a boosted car. If I could make a perfect fuel for me it would be E70 using straight 93 octane mixed with E99 blended together. You get all the benefits but doesn't tax the fuel system as bad. I have no desire to blend custom...

I just felt I was trying to help. No worries, I won't anymore.

The scanner will do it for you with the boost pressure PID. The car has a map sensor so the boost pressure is accurate. No need to do any math. It actually uses a MAPT sensor so it measures temp as well which would be used as IAT2.

There is a PID for boost pressure in the scanner you don't need to do the math.

What's the 60 to 130 now?

I'd run with the lids on but I'd open up both sides of the mesh grill and the intake temps do recover a little faster while moving.

How much boost with the supplied pulley? You should dragy it to see what it runs. I haven't seen a roush car even retuned run a good time yet.

I run those tires 22 psi cold ALL the time I also get about double the miles out of them that way and they work the best for me at that pressure. If you run more psi then that then the middle will wear out first and you'll need tires in 5k miles or less. I've had quite a few sets of those over...

Looks different then I thought it would on an s650. I guess I'll have to just wait to see one in person.
