f23a swap

[deevergote]

The F22A1 ECU (PT3) wouldn't even have a fuel map for the VTEC lobes. When you switch to VTEC using the wrong non-VTEC ECU, if the crossover even happens, you're probably running the risk of running dangerously lean.

yes it runs a little lean all the time. thank you all for all the advice. I will look for the conversion harness. should i use the ecu that came with that motor? its obd2 btw. so not sure how that would work. what conversion are you refering to.

also I do not have vtec on a switch. i poped it with a power probe while riding down the road. it made no power. but no surprise there. as soon as i get this thing running properly it will get 8 pouds of boost.....untill automatic pukes the clutches/ then we get the 5 speed.

lean or rich? can you smell gas? my guess is your running rich because the lobes on the f23 cam are not as aggressive so your not moving as much air. and they make a conversion harness to convert from obd1 to obd2a. there a little more expensive than the obd2a to obd1 harnesses but they are out there you just have to look a little harder for them. YES you should use the ecu that goes with that motor because it will be programmed specifically for that motor

Or there's always the option of getting a chipped P28 and having it tuned.

Think i mentioned this before... best option in my opinion.

i like the way of just puting in a wide band and wiring up a apex air flow controller and just doing that way... any comments? i did that with a few other cars... eclipse. galant.... f150 super charger.... also a 91 prelude it all worked great. also no check engine lights..?

i willbe running boost in a few months so it sounds like a wise choice to me

[deevergote]

That's actually a terribly inaccurate way of tuning, especially for turbo... but do as you will. It's your car. Just please... don't pass yourself off as an expert to others. I don't mind if you blow up your own car, but if you give bad advice to others, there may be a problem.

[remove_bulb93]

o ok then. well id like to do this correctly.... whats the going route when boosting? how do you all tune the oversized injecters?

[Jarrett]

With a tuning program like Crome, Neptune or Hondata on a chipped ECU. Your wiring job is going to have to be redone in order for things to work properly.
