Need help with VX S1 V6 - Error Code 24 and 20

[Tazzi]

Yep sounds like hes messed something up pretty good. If the revs are sitting around 2K, then its been programmed as a V8 instead of a V6, Or some weird number has been programmed in due to a failed programming sequence.

Must have really screwed up to do all that!. Id suggest to get him to check the airbag config, change that first. Then configure the Engine size (will fix rpms) then reprogram the fuel settings as a sedan. Also make sure that its on the correct car eg 02 VX ect not VT or something alike!
Should be able to fix it with the scantool.. unless theres been a major screwup!

it it was programed as v8 then the tach should read lower as more pulses are required per rev for v8 tach

Not always the case.
For VY's, tacho pulse is 3 for V6 and 2 for V8
Whereas for VZ's, pulse is 3 for V8 and 2 for V6

(Or maybe the other way round) but they are opposites.

The VX clusters might be similar to the VY tachos.

odd?

shouldn't be 3 V6 and 4 V8 ?

[Jayme]

no.... the ls1 pcm tacho output is set to 2 pulse. its not the same amount of pulses as the coils....

[antus]

x2. Thats absolutely right and why it would be reading high if set for v8 on a vx v8 - as if it was a v8 it would be a 2 pulse per rev ls1. The reason its that way is because its taken from the cam sensor with a divider, not the ignition.

Ah thats cool, Didnt kow that. I did make some notes of what the tech2 did and what it was changing a while back for the vt/vx clusters tacho. It was quite weird on how it was all formatted, wasnt exactly like the vy/vz's but same concept applies.

These are the results so far

20:27:09.953 Tx'd Frame = FB, 57, 1, 2, AB,
20:27:09.984 Rx'd Frame = FB, 62, 1, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, A0,

Means no "current" faults present. How about sending FB,57,01,04,A9, will request "History" faults

Ok will do that.

I don't get any faults on Tunerpro as well.

I've attached a screenshot of the Autel Scantool
