A few random $8D questions

[EagleMark]

I've not found one I can't fix accuratly. Just get a log and I'll double check it.

[JeepsAndGuns]

Will do!
I'll hook it back up this weekend and record ya a log. How long do you want it to be?

[EagleMark]

Whatever, just a few minutes or whatever you have.

[JeepsAndGuns]

I dont have any saved, so I will record one this weekend.

Ok, here ya go. Recorded this today.


Accrdwgnguy, you were right. I hooked up the vss to pin C6 and it works, even shows the correct speed. That kinda surprised me a bit, I was expecting it to read half what it should have.

[EagleMark]

None of them were built right and none had inputs needed?

BLM lower and upper now work.

Spark Advance works but have to check, there 2 vaules and they are off by 10... I hate when timing is off by 10... also need to set conversion from 0.0000 to 5.00000 if distributor is set to 5.0000

The other MPG and WB AFR ones won't work becuase the values are not in the ADX, so I removed them, the tables were not built right anyway. If you get BPW and WB in datastream we can add Injector Duty Cycle, WB and MPG stuff...

[Accrdwgnguy]

No problem, glad I could help. When I finally got a working VSS hooked up (my first optical box was dead), the pulse counts in the ECU seemed to reset itself to the correct pulse count, before I would correct it manually and it would just revert to 4k. Kind of odd.

Just hope I can get a little assistance with my future 258 MPFI swap. I'll be using a 730 as well. :)

[JeepsAndGuns]

Mark, thanks big time. I knew if anyone could fix it, you could. It was just way over my head. I will DL it to my laptop this afternoon and playback the log and see how it ran.

Accrdwgnguy, when you say 258, are you refering to a jeep 258 straight six? If so that will be cool, as I am planning on swapping the 4.0 in my 93 YJ to a 7727 running $8D.

[EagleMark]

There's probly a hack or data stream not included in this $8D ADX for BPW/BPC that would be what is needed for Injector Duty Cycle... if you can find it?

Also a pin to wire in WB?

[JeepsAndGuns]

Checked it and the history tables are working just like you said. Thanks a lot!!

Is there a unused input/pin to where the WB can be hooked to the 7730/7727 and have it come through the data stream like I am doing with the 7427? I have installed a MTX-L into my wrangler and being able to have it on the log like I do in my cherokee would be sweet.

[EagleMark]

I'm sure someone has done it but I don't know where/how?

[Six_Shooter]

S_AUJP is set-up to have WBO2 info passed to the datastream.

Yes I am. I have my eye on an AMC Eagle wagon, really tempting, if I can't resist then I'll inject it using the extra 730 I have lying around.

Sweet. I would highly reccomend installing a 4.0 head and intake/FI onto it. That would help wake it up.
The Jeep 4.0 (91-95 for sure, possiably other years) TPS will work, it uses a standard GM MAP sensor. MAT and CTS will need changed to GM ones. The 4.0 IAC will also work. I spent some time by trial and error figureing out the correct wires to hook to where to get the IAC working with the 7727/7730, but I have the pinout for it if you need it. You can use the stock motocraft distributor from the 258. Shouldnt be a very hard swap.
