Question Bama 4-Bank eliminator chip for '86-'88 SD cars

It's probably best to just convert my '88 GT to Mass Air. Any '86-'88 SD car owners using the Bama 4-Bank eliminator chip or something else? I just want a pump gas tune (87-93) and an E85 tune for my car. Basically make it a flex fuel car for the times E85 is available. There's an E85 pump not too far away, but I'm not going to drive there every time I need to fill up. Thanks!

That really won't give you flex fuel capability, and being SD or MAF has nothing to do with what you have in mind.

Doing what you describe you'd also have to drain your tank and purge your lines every time you wanted to switch fuels.

If you want flex fuel you need to add an oxygen sensor to the fuel supply so it can measure exactly how much alcohol is in the fuel and then adjust your fuel delivery to compensate. A BAMA chip can't support that, you need a new ECU to do that.

A compromise would be to add a 2nd fuel tank just for E85. You would still need to purge lines which changing fuels but you wouldn't need to drain tanks, just turn valves to change your draw and return from one tank or the other. A BAMA chip could support this because it never needs to deal with some blend between the two fuels. But it's really important that you are anal about purging lines when switching fuels, you can't mix them or your tune is off.

Final thought, you won't make any more power on E85 than you will on pump gas without something like a turbocharger.

I'm putting my mass air conversion on hold for now. I'm not sure if I'm sticking with the 302 sbf. I'll do more research on E85 also.

I think your final thought is incorrect. Please watch the video below. The 2018 Mustang GT doesn't have a turbocharger.

Those have 12:1 compression, so yes with E85 there's power to be gained in more advanced timing. Unless you rebuild your engine for high compression you'll have nothing to gain. That's why I mean "something like" a turbocharger. Something that puts cylinder pressures high enough that you can't run minimum timing for best torque before creating pre-ignition. On an N/A 9:1 compression ratio small block ford you can make max power without even running 93 octane let alone the need for E85.

Thumbs up

I forgot about the compression ratio. Thank you for the info. I'm leaning towards the newer stuff (Mod motor or coyote) more and more. I'm not ruling out a turbocharger. I have a lot of decisions to make. I'm glad to didn't order the '86-'88 mass air kit $600+.

If I were starting fresh I'd do a Coyote.

They are expensive. Even if you go the junkyard engine route. You still need a ton of parts.

I haven't looked into it really, but you can get engine and trans with accessories and harness for $5k. Fab up a throttle cable, buy the swap headers and mounts, and in my situation I'd just hook up my megasquirt and go to town. I think it would be no more than building a "real" SBF, likely less.

But I don't think I could resist stroking it to 351 first, lol.

F150 coyotes are about $2500. After swapping the cams and oil pump gears, front accessories, one might be better off purchasing one brand new. I'm still doing the research.
