It is a batch fire.
The sequential is nice for emissions but you don't really gain anything in performance. And it takes more sensors on the crank/cam/distr to be able to time the pulses.
I'm working on a SFI system now but it won't be done for a while. Just not a priority.

Yes you can tune it.

Ok works for me. I'm in then. You should just boost one of your mpfi setups with me haha.I don't care either way about sfi either. I can't wait to see what one of these boosted sv engines will do on the dyno

here is the link to a throttle body i was wondering if it would work or not? comes with tps and hole for iac

Equipped with a standard carburetor style linkage assembly, this square bore design will work with dozens of factory or aftermarket 4 barrel manifolds.

Yes and no.
Yes it will work but only if you bolt a carb spreadbore to squarebore adapter on first.

I already have a couple of those but I planned on just getting a squarebore anywho. So sweet. Then I will get something like that

Designed for use in custom applications, the BBK 4 barrel performance universal throttle body delivers unmatched performance at an affordable price. Equipped with a standard carburetor style linkage assembly, this square bore design will work with dozens of factory or aftermarket 4 barrel manifolds. It also features a universal style BBK throttle position sensor for easy hook-up on your custom application. Universal 4 barrel design – 1-3/4” Bores. Great for custom applications. Includes GM late model style throttle position sensor. Machined for late model GM IAC
@Bill- will you be able to make the ecu work with the late model iac and tps?

[teenbmxer]

also could you tell me exactly which ECU to purchase to set this up, maybe a link or years of 3 bar map sensor to use

[Bill usn-1]

Yes any ecm/pcm will work with the TPS and IAC.

I can't speak for you but I am starting with the ECM mentioned earlier.
1227730.
With a power adder I will run the code59 software in it.

MPFI and turbo.

I'll have to look up the map sensor part #.

I already have my latest version of the wire harness for this ECM for MPFI on the IH and AMC V8 engines.
Going thru final checks of it now.

[teenbmxer]

Ok then all is well and we shall be doing business real soon.

just an update i picked up the 1227730 ecu at work today. and now have my wastegate, blow off, intercooler, and turbo
