    I don't think you could just plug the ECM in and have it control timing. It would want inputs from throttle, MAP, and temperature sensors at least. I don't honestly know what it would do if you had all that plugged in, but lost the injectors and subbed a carb. It might completely freak out and go into some sort of dumb limp mode. Either way I don't think it would be good for performance. You'd have no way to adjust what the timing is actually doing. For all the headache to try and retain a TFI system in some sort of really useful manner with a carb, you're better off dumping it for a normal distributor.

    if you want something fancy though, modern electronic distributors with programmable timing curves do exist. They can be tuned to do things that a standard distributor just cannot.

    or you just get a normal distributor and a set of springs and curve the thing how you need it to be like people have been doing for decades.

    A "hotter/hi performance" coil won't add anything. I feel you can pretty much ignore the ignition system until you really start hopping up the engine, so long as it's already in peak shape. When I was in my teens I put a full MSD ignition system in my Firebird; 6AL box, billet dizzy, their coil blah blah. Didn't notice shit. However, their coil took a shit on me within three months and so too did their fancy & pretty red dizzy cap. it's been running a stock cap & coil ever since.

    As others have said on here, swap up the rear gears for 3.73's or 4.10's, add dual exhaust and maybe swap out the intake for one which flows better. I think the throttle bodies on CFI stuff share bolt patterns with Holley carbs, not sure. But if that's the case, you should have plenty of options to choose from.

    yeah the stock TFI ignition is actually pretty healthy. I guess you could stick a red coil on there with the chrome valve covers, they do about the same for power gains.

    CFI unit has the same bolt arrangement as any common 2bbl. A good 2bbl intake or a 4bbl intake with a 4 to 2 adapter would work. How much it helps, hard to say but unlikely to make it worse.

    I'd keep it maintained, running up to spec and leave it be. It's not going to be running at the next Indy 500. Most likely, the money and time spent trying to "improve" it will bring minimal gains in performance.

    LoL yeah I forgot about mental performance gains. Just paint the stock coil red and slap an MSD sticker on it, all of the performance gains with OEM reliability.

    For what it's worth, the Ecklebrock Performer TBI intake I slapped on the Fireturd helped move/and or improve torque such that it could then roast tires on concrete and sometimes bark them from a stop. Didn't do it before the swap. God that thing was terrible. The best performance mods it received were Trick Flow cylinder heads and a rear gear swap. Moving from 2.73's to 3.23's (Thought they were 3.42's..) woke up city driving quite a bit as well as improve city MPG.

    I'm also a fan of friskyfrankie's idea. If anything, 3.55's and dual exhaust.

    The 88 MGM I had, I put 3.55 rear gears, duals, and wide ratio trans gears. That car was really fun off the line but had no top end. It would gripe at me for going over 75mph. But it would scare 2000s M3s and Corvettes off the line to the other side of the intersection before it fell on it's face.

    frankly thats probably the best way, even better if the cam is upgraded. the heads aren't amazing but the E5 heads really aren't that different than the E7, at least not different enough that I'd say it justifies swapping stock for stock.

    I dunno, my dad's '99 base C5 with it's slushbox seems like a rocketship off the line compared to everything I've ever driven in the past. Kind of takes it a second from a stop, but if it goes 2nd to 1st, Wooooo! If it wasn't for nostalgia and such, I'd sell both the Fireturd and Lincoln for a six speed C5 ZO6. I used to think the C5 was the worst Corvette, right there beside mid 70's to early 80's C3's. Then I eyeballed one up close and drove it.

    But I know what you mean, it's as if the AOD and 700R4 transmissions intentionally have a low first gear, so when combined with a hot rear gear, 1st is really fun. Once the Firebird gets out of 2nd, it's all over. Before the mods, even 1st was terrible if I tried to race anyone other than myself.

    With the 4R70W gears in the AOD, it's even more pronounced. 1st gear is a good deal lower than the AOD. I would like to have a 4r70W put in my 93... but I have no real desire to any more.

    Oh, you can do that? Neat. Is the 4R70W's OD ratio steeper than an AOD's?

    slightly shallower actually, 0.67 for the AOD vs 0.70 for the 4R70w.

    yeah. 3 and 4 are basically the same. it's 1 and 2 that are a good deal lower than the older ones.

    EGR delete and no cats, air pump dual exhaust all help. Non ethanol gas helps. Replace the OE nylon over aluminium eingle row timing set with double row set

    Keep the catalytic converters. The rest of us will thank you. Nothing like getting stuck behind a mechanical asshole and then stinking as a consequence. Not all of us have the luxury of cabin filters.

    honestly the EGR doesn't cause problems if its working as designed either.

    the air pump in theory shouldn't hurt, but in reality it doesn't do much of use either, it makes stupid noises when working and really stupid ones when it fails.

    smog pump that was on the 88 MGM I had sounded like a turbo when it was failing before it seized up. Was kinda neat for those two weeks.

    one of mine sounded like a drunk with a maraca, the other sounded like a flying saucer in a cheesy sci-fi movie from the 50s.

    I never noticed any sound from the smog pump on my Ď88 Grand Marquis. The one on the Mark VI sounds like a coffee can full of rocks on startup, it goes away as the engine warms up. Eventually itíll probably seize up, at that point Iíll remove the entire ordeal. Until then Iíll likely be too lazy. Iíve had the belt off and it turns freely and there doesnít seem to be excessive endplay in the thing so I donít know what itís issue is.
