Datamster file at http://www.acaenterprises.com/upload/fixed.zip

230/236/112 porrted heads 6spd car has new o2 sensors

the car will not idle in closed loop, and has trouble idling in open loop. it has a pcm4less tune in it right now

I know teh datamaster file is not that long but thats all i could get tonight. As soon as I would push the clutch in to stop the car would die.


also in open loop, it would hover down near 500 rpm and slowly rise back up, but i dont think it ever died in open loop

any ideas?

 

The car also feels like its lacking a little in power...

I do have an air leak at the tb elbow i believe, that will be getting fixed next week.


On a dyno, do they tune the whole car at idle and part throttle or just WOT? I would think the whole spectrum but gotta make sure, Im about ready to just get a dyno tune so I can drive this ****er


and whats up with all the knock retard?

 

when i frist started the car with a new battery it started easily, however when starting after the engine dies, it takes forever for it to start up

 

Fix that leak, look for any vacuum leaks and then get some numbers. what is compression for each cylinder and what is the fuel pressure while all these problems are going on? When you can get it to run for a few minutes, try pulling each plug wire and then plug it back in one at a time. See if there are any that when unplugged, do not have an affect on the roughness of the engine. Obviously, use plug pliers when doing this.

Also, check to be sure some of the injector plugs didn't get mixed up to the wrong injectors. This is not fun to figure out.

check all the connectors that have recently been disconnected to do any work and see if any of the pins are damaged.

Sorry I can't be of much help to you

Good luck
