Still going, fresh motor on the test car!

Quite update.

Fresh motor on car is good. Been getting some street tuning done, but is slow because Ecutek flashes rather slowly, and this is being done organically.

More dyno time coming soon.

Glad to hear everything is going well. Patiently looking forward to updates!

where is it located the map sensor with this itb? or is it maf based? or alpha N?

So... Down time at work has me researching car parts (again) and I just discovered that CSG has a power package option. Dangerous stuff, especially since the ITBs cost as much by themselves as a full exhaust would. That being said... It is tempting. I can't help but wonder how much power you would get out of a full exhaust with ITBs and tuned for E85.

That's being actively worked on.

It won't be anywhere near as much as FI, but none of the complexity, and you'll never heat soak.

I see we have something in common.

Well, I'm one of the very few that's satisfied with stock power, but if I said I wasn't curious about more power I'd be lying. I don't need huge power, but to justify almost $8k in parts I would like to see those numbers, and some big ones.

ITB's are not about hp/dollar gains, but the change in response and attitude of the engine. If hp/dollar is your objective, a bolt-on supercharger (Jackson, Edelbrock) with E85 will cost less, and double your engine output.

Oh, no doubt, but I want to stay NA if possible, and like I said, big numbers really aren't my goal. I guess I'm just trying to justify the extra cost since the ITBs cost more than the entire exhaust setup combined. I'm a cheap person by nature so my mind won't allow the splurge without justification. Response time improvement is a tempting factor since I do think the revs need to climb faster.

If you want the revs to climb faster, a light clutch setup will be the way to go. Specifically, an OS Giken.

ITBs dramatically change throttle response.

Try giving your throttle pedal a large momentary blip, and observe the delay between stepping on the throttle, and the revs climbing.

It's an auto, so no clutch haha

But I know the lag you're talking about. Getting rid of that is tempting, but I'm not sure if it's worth $3500. I'll keep it tentative for now and definitely will keep following this for more info. The more info I can get the better.

And this right here is why I hate forced induction. I have never once driven a FI car that has that immediate throttle response that I crave in a fun vehicle.
If it doesn't have good throttle response, might as well slap an automatic on it and let the damn transmission sort it out.

Fingers crossed that this doesn't require a full ecu swap; I don't like having to dodge vehicle inspections 'cause the diagnostic port is a road to nowhere.
