When you install a street Cam that the stock ECM can't handle what parameter(s) run out of headroom?

I'm thinking that the max. Cam duration that my stock ECM can handle is about 220, and that a .470 lift is no big deal. I'm going to use SR Torquers so I'll have more intake flow over stock heads.

The ECM will regulate injector pulse width, and engine timing but those tables are all that would need to be modified aren't they?

I'll be working on an 87 305, 5-Speed, Crane 2032, 1.52 rockers, SR Torquers, Gasket matched intake/exhaust, stock manifold, new 3" exhaust system.

 

First thing that will run out will probably be your injectors! I'd probably go with ~24 lb/hr with your combo. Change the injector constants first (probably switch to $6E code, and disconnect the cold start injector - then tweak MAF table 1).

Then, the next problem area will likely be your idle speed adjustment, and idle ignition timing.

It's also likely that your acceleration enrichment will like some change. But you'll be throwing darts in the dark without a wideband (LM1's sliding display really makes it clear which areas of AE need the change).

And almost everyone likes to run a little leaner than stock in PE. Stock Power enrichment is on the super safe rich side. Get a wideband and dial it back a little (to approximately 12.5:1).

Then, when that is done, you can consider giving it a little more ignition timing at higher loads.

Your MAF system is fairly forgiving, and should be easier for a beginner to get running well enough. If you're totally **** about perfect control (better than MAF at least), you'll want to go speed density (MAP based).

 

RednGold86Z,
You think that I'll need to change to 24 lb. injectors? Hmmm, I hadn't even considered that. I had been thinking that 19 lb. injectors with a little more fuel pressure would work well.

I have been thinking that I'd go to a set of Ford SVO 19 lb. injectors and a Holley AFPR to add some more fuel to the mix. The posts that I have read seem to say that the SVO injectors flow a little more than my old stock ones do.
