p72 ecu and revlimit issues

Nors · Post by **Nors** » Sun Aug 06, 2006 5:12 pm

So my friend just got an s300 unit on a p72 ecu for his prelude. After adjusting the injectors to the stock size (was orginally 450) we were setting the launch control. The first time we set it we set it at 3500. Now even when we disable it it stays, even when he is just driving the rev limit becomes 3500. After changing it back and uploading it nothing changed. We can still edit other things (to check we changed the idle). Now he is throwing codes for fuel injectors and baro sensor and we don't know why. If anyone has any ideas it would be great.

Is this a US or JDM P72?

The CEL codes are

3 MAP - manifold absolute pressure sensor
Code 16 Fuel injectors

so this is a s300j not an s300 and a JDM P72....both very important details.

you must disable Baro, eld, and injector error codes.

Make sure you have it set to Realime Update from the Options menu.

Im his friend that hes talking about. How do i disable the code ? If its giving me a code doesnt that mean that there is a problem ? I have the injector setting: stock 290 and current 290. This is on a 98 prelude sh.

i have a USDM p28 with the s300. i set the launch control but notice i end up with a VERY low rev limit.

can i adjust that out as well? i can set a 4k launch with a 6mph shut off, but while driving i have a 4k rev limit. frusterating :(

oh, and i have all the options listed above checked so as to have them disabled.

ok it worked good. But now the car bogs terrible at around 4k and wont rev any higher. The rev limit is set at 7400

This sounds like a tuning issue...I would recommend getting the car properly tuned on the dyno as soon as possible.

Are there any error codes.

You guys really need to follow the directions and post your calibrations and datalogs showing the problems you are askign about.

How do you have this clutch switch wired to the ac input?
