114 counts is not what I would call abnormal(common to see 115-120 on a good operating motor). But 157 is way high and thats what I would be looking at.

Yeah, I'll start it up and try to hold it at the lowest steady rpm I can get so we can see what it's doing. I was really expecting to see the fuel trim very rich since the exh smells terrible. On the CPI inj there is only 1 solenoid and it sends pressure to all 6 poppets at once. The fuel pressure is dead nutz 60psi running. I changed the INJ spider when I installed the motor. It's a Borg Warner from Oreilly's.

Neither one is "abnormal". What's abnormal is that those numbers are both in the same trim cell within a couple minutes of each other...The number itself tells very little.

Just thought I'd ask---I have seen stranger things throw folks off...
Have you double-checked all the ECM grounds...engine/frame to body grounds, batt to engine...batt to frame?

Possibly a bad ECM/PROM?

Posible but not likely in my opinion..You guys should download that file and take a look at it.

Eat'n dinner then back to it.
Yes, triple checked the grounds. Could be a bad ecu but I have the original prom and swapped them 2 weeks ago. It runs the same either way.

Doesn't this one have a vacuum referenced fuel pressure regulator?

Negative. Preset spring diaphragm.

What's the broadcast code? Should have a 4 letter code on the computer, BHDF, BHRJ, BJDR,....

It's weird, the timing isn't jumping around like it did Sat. but why the hell would it be 29-30 deg adv at 1.2% tps and 975 rpms?

I don't remember if you have the pinout....

Same setup as a TBI and is integrated into the injector unit.

yes/no. We use it in the field quite often..

At what MAP value? The basic advance table is per RPM and MAP......It could be right.

Not a member of Binder Planet so I can't open the files but yes I do have the correct pinouts I believe.
I f-ing with the timing to see if it makes a difference....................

Varied between 9-10"HG

That's by a vacuum gage?....Sounds like the advance is a little high but could be right.....I trid to find the .bin file for BHRH but no luck. That would have told us this kind of thing.

You have it...can you email it to me?:corn:

So, I retarded the timing about 14deg and now it idles at around 600rpms but the timing is bouncing from 2-26deg rapidly.
