works great but with the p72 ecu the car has a rev limit of 5k and doesnt shift correctly. how could i get this to work correctly, has anyone done it? with the LS computer in it the car runs good but no VTEC, i could install an VAFC but the car would still ahve a rev limit of 7k with the ls ecu. this is an obd2a car. Just looking to get some input from other people.

 

get a msd

 

Some of the JDM engine importers can probably get an automatic P72 from an Integra SiR VTEC that would suit this application perfectly, without having to ghettofy anything.

 

jdm auto p72 will still have a low rpm rev limit and the reason it doesn't shift right is the trans goes into limp mode and only has 2nd and 4th gear.

And can you offer a logical explanation for why you think so?

philipwight stated that the original automatic ECU allows the car to run correctly, just without VTEC, naturally because it's a non-VTEC computer. The P72 he probably has is a manual P72, completely lacking the ability to work with the automatic tranny, thus causing the incorrect shifting and the limp-mode induced 5k rev limit.

A JDM automatic P72 should correct this situation as it has all the necessary capabilities that the stock automatic ECU has, and it has the additional provisions for VTEC including a higher rev limit.

 

No I know what he posted I was explaining to him what happens to the trans with out the auto ecu I think you have a ego problem not everybody knows as much as you or I.
I didn't know this was your post and no the JDM P72 auto does not have a rev limit as high as a manual one does but I do agree it is higher than his stock ecu and offers vtec.

 

chipped auto p28 maybe
