I'm trying to replace my A9L because no one here in Southern Nevada can tune it. They have a problem with OBD-1. Will a Mega Squirt work? Is it OBD-2? I'm not a computer whiz so I don't know if there is something out there that is basically plug and play?You can get a Plug-n-Play MegaSquirt for $840. Since you don't have a stock HO, you'll also need a wideband O2 sensor too. Another $150-200. You'll also need to tune it or somebody to tune it. If you aren't a 'computer whiz', I probably wouldn't recommend it.
I'm not positive but I think the modifications I have done exceed the capabilities of the A9L.
Appreciate the help.
MegaSquirt isn't OBD-2 or even OBD-1 (which is just a catchall for any ECU that has some sort of diagnostics and is able to tell the end user.
I'd wager a large bet you haven't exceeded the capabilities of the A9L. Even though it's 30 years old, it is still more advanced than any MegaSquirt, Holley, etc for basic drivability parameters (it doesn't have capability for data logging, boost control, etc, but if you've ever looked at the GUFB strategy document you can see how complicated it is. Designed to make the vehicle drivable and emissions complaint in any possible environmental condition. It has orders of magnitude more development man hours put into it than MegaSquirt/Holley/etc)
The downside to the A9L is it can be hard to tune because of the complexity of the strategy. Megasquirt is much easier to tune because it doesn't have all of the emissions or complicated edge case drivability dependencies. Holley is easier than Megasquirt.
Cougar 5.0 went Holley, but his exact route requires putting in a carb intake and a full re-wire. (Correct me if I'm wrong!)
Holley has other options, but I'm not super familiar.
Personally, if you aren't interesting into dumping a bunch of labor/$ into your car, I'd try and find a shop (even if it's down the road a bit) and tune your current A9L as you're N/A and don't have an extreme setup.
Now I'll have to wait until I get home!
For motorcycles/bicycles/ATSs/UTVs, sag (the amount of bump travel from full extension to ride height) is ~25-35%. I'm not sure what is for cars (which is the point of this thread ), but I'd think it'd be below 50% since you want more bump travel than droop travel to soak up the bumps on the road.
The FSM for most years is available on CD, but other manuals (EVTM, etc) are hit and miss. Shut up and take my money!
I guess we're supposed to pay $22 for a 72 hour window to look at and download the manuals? https://www.motorcraftservice.com/Home/Pricing/7

Aren't '87-'88 the same PN?
