Vacuum Issue??? NSFW!!!
« on: November 07, 2009, 01:57:01 PM »
Ok just started up a map with BRE in a PR3 ecu. the problem is at idle it is sitting at 16-14 inch vacuum. i can not get it to sit in 23 or 21in.v... Also the distributor is all the way retarded if we set it to 16 degrees it will sit in 14-13in.v...

We have checked timing its on. We changed map sensors to a know working 1 nothing. changed ignition timing in the map still nothing??

The car is a 91 crx PR3 ecu with a B16a. stock map sensor, tps, also a distributor king dizzy. when he had this motor in his integra it would idle at about 37-35Kpa in ectune?

I tried to attach the maps but said i exceeded limit every time.



And for your effort i give you some Porn for my gratitude.......

compression test to see if all cylinders are good?  could have a compression problem causing the low vacuum.

Nope, low "vacuum" according to datalogs and cold start issues - mostly when in the 90-140 degree range after start - are what I experienced.
