hey i was wondering if anyone has had experience with ITB's on a non-vtec motor build...lemme know cuz i was thinking of doing that...and how hard is it to tune the ITB's on like hondata or somethin?

crome or neptune is supposed to be the best for ITB's

it allows you to run half of your fuel map off your tps and half off your map for better part to open throttle transition

although crome is cheaper I would say run neptune, I have a couple of local friends tuned on it, and all of their cars seem to run better than they did with the crome tune (no weird idles etc ...)

ok cuz i have hondata and i have never really seen anyone tune itb's on it except like an s300

the problem is that when you open the throttle plates up you transition from hi vacuum to 0 vacuum almost instantly. your computer basically cant keep up using a standard MAP based system and as far as i know hondata doesnt provide any alternative way to tune.

yea ive seen some hondata s300's try to do it but they were not very sucessful...thanks for dat info...

I had that exact setup! 12.5:1 JE pistons, eagle rods, Crower 404's, KMS valvetrain, and a homemade set of Hyabusa ITB's on a B20. I had it tuned with CROME then an AEM EMS and I'd have to say the AEM did the best as far as daily drivability goes. The CROME setup worked decent though. Idle was a little hard on cold starts and sitting at redlights.

how did it work power wise, did you compare that to a IM at all?

No man I didn't compare it at all. I built that motor for those ITB's. I'm actually using that head setup on my boosted application.
