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.
-
Steady idle. will have him do a compression and leak down to confirm..

Last BRE car I did behaved similarly.

Mine was working well, but it was a OBD0 PR4.

Really do you by chance know why? i got the map and a couple logs but RHMT keeps saying im exceeding the upload limit even if i try to upload just 1 that is way below the limit.
-
It was the second BRE car I've done, the other was ~4 years ago. I really know jack shit.
-
Damn... gotta be something simple im over looking.
-
Runs fine = runs fine. What are you overlooking?
-
Just seems to be running to low of vacuum at idle. thats what caught my attention. that and the starting issue but that should be an easy fix.
-
thread jack
Iv been trying to get bre to run on my computer
Where did you get a copy from and anyone got a stock pr3 in for it?
-
I would dbl check you timing
it could cause low vac if a cam is out
-
Nope, low "vacuum" according to datalogs and cold start issues - mostly when in the 90-140 degree range after start - are what I experienced.
