Are there any other pins on the 7730 ECM that can read a 5V sensor and then communicate out to Tunerpro?

And if so, in Tunerpro, how would one go about telling it to look at that particular pin and report it out?

A input like d4 maybe ?

In fact, is there a schematic of the 7730 somewhere I can get hold of?

Extratorq iirc use to have a post of the schematic.

Hmmm.... doesn't appear to be giving me the I/O list of all the connector pins...


I found this...

Looks like B3 is a 2nd MAT sensor; or a 3rd MAT sensor at E14. Maybe I could tap off of one of those...

The question then is how do I get Tunerpro to see one of those pins?

It does, sheet 8 shows the three harness connectors. Sheet 3 shows how the inputs are configured.

Need to add firmware that will read the desired input and place it in a RAM location that can be spit out via the ALDL data stream. Then need to add that to TunerPro so that the proper value is displayed.

That sounds like an SAUJP update...

SAUJP already does that.
It's also easy to add it to any other $8D bin.

The link I posted with the internal schematic of the 730 doesn’t work.
Anyone know is f9 a v5 ref ? And is b8 12v ?

According to the pinouts in the link above,

F9 => U6-12 via 100 & 200K, CAL-29 via 100 ESC (100 & 4.02K to 5V)

B8 => ESC Tap (10K & 470K to GND) U13-15 via 10K, CAL-32 via 10K

Thanks I guess I overlooked b8 being listed.
Funny it says 4.02k when a sd ls is 3.9k must be close enough.

Do you know if a tpi maf esc module will work on f9. I think it uses a 100k ks.
Does it need higher voltage. How can voltage be changed in the reprogramming . Unfortunately I can’t read code but is there a hex address that can be changed ? I read that the 165 ecm puts out 9.3v koeo and running.
Of course with the memcals esc removed.

I have no clue on that one... Maybe RBob or one of the other experts knows...

I think chevythunder is wrong. b7 Pinout on a 165 is 9.3v and diagnostic shows below 6v.
165 must be a 5v ref signal ?
