Hello everyone, I'm looking to mod my car and one of the mods was going to be an E85 kit, I'm getting all the mods from summit for now and was wondering if anyone has ran AFD-PFD-GMLT-1, if so, how is it in comparison to other kits?

They all use the same gm sensor. The hoses and fittings vary a bit in quality. The dsx is the nicest I've seen.

I've been a sucker for motion race works. They have a nice mount for the sensor that would not decrease any protentional flow issues for the guys with upgraded fuel pumps.

For the guys with oem fuel systems, running the regular sensor in line proves to be best choice. DSX seems to have a really nice kit

I have the Dsx on my C7.

I'm using the kit from Lethal. I like it so far.

dumb question. once you have flex fuel kit install and car is retuned. is it possible to run on high octane if you can't make it for flex fuel and can you mix the 2 together when try to get back to flex fuel once you hit a station?

Never used that kit but like others mine is DSX. IMO, It’s really about the quality of the kit. The quality of upgraded fuel line, machined connections and prior experience from others influenced my purchase.

Not a dumb question and is actually rather common. You can have any mixtire of gasoline and ethanol in the tank. The purpose of the sensor is to communicate the percentage of ethanol to the ECM where fuel duty cycle and timing adjust itself based on the ethanol percentage.

So you could have a half of a tank of 93 in the car and decide you want to top it off with E85. The ECM will adjust for the fuel/ethanol accordingly. If you wanted the entire tank to be E85, same logic applies.

ok next dumb question, that im not sure you can answer, why the hell would gm not put this on all cars they make?

Good question and idk if there was ever a solid answer on this but here’s an old thread about the topic.

(OP, trying to stay on topic)

The old thread then brings up the question- Has anyone running an E-85 mix for any length of time had any issues from fuel lines or fuel pumps that could be associated to their E-85 installation? So this DSX is the way to on kits?
Thanks!

My '17 SS is 4yrs old now and while I don't have access to E-85 routinely, I wouldn't mind the occasional fill-up when I do (yes, I'm easily entertained). I'm guessing with this mod's popularity there haven't been wide spread problems. Am I wrong?

Nope been running mine straight E85 for 3yrs now with no issues.

Yes. The ECU has Gasoline and Alcohol stoich, spark, and power enrichment tables it refers to after it reads the mixture of Ethanol percent reported from the sensor. So you can switch back and fourth between E85 and 93 octane and it will see the blend and adjust the tune on the fly. Now if you are asking if you can run 100 octane race fuel, then answer is also yes but it's a waste if the gasoline portion of the tune is based on 93 octane.

They don't put a flex fuel sensor on every vehicle because it's like a 1500.00 option that they charge for on the vehicles build order...so the answer is $. It's a bunch of shit too because a DI engine running E85 will still like have less carbon foot print then the Electric vehicles that GM is pushing to be switched over to by 2035.

What King said, I run both depending on the time of year. E85 (e65 to 70 here in Missouri) starting in March I'll run pump E all the way up till about November and then back to 93 octane again.
