New Coil - Tachometer Jumpy affecting TCU

[patch697]

If its a resistance issue why can't Bigus just use a 1watt 0 to 50k trim pot in line & just screw the thing up until it finds its mark?

Even a 1/2 watt will do the job

Problem is old mate - started before the module was replaced and it's a stock standard Bosch replacement.

Yeah..... Got that after I read your last update post.

Tell me more mate - Derek mentioned an in line resistor also, but both Rodney's (YENDOR and Wholesale autos) suggested not to ...

I'm willing to try anything ...

there not overly specific thought Rod.

In most cases you'd work on around 5K +/- 1k but mines 7.3k

Im surfing the net new trying to find out more.

My mine concern is with the primary resistance.

Here's the thing old mate............. They use a 1/2 watt 2k resistor inline with the Tacho factory.

Rod know he's stuff & if he says not to then theres a reason behind it im sure.

Todd slow down, I can't post that fast.....ahahahahahha

I'm not sure if Scotty can get online at the moment.

Not typing fast, cut and paste from an email I had.....Scotty is meant 2 be offline and @ my place drinking bourbons! *L*

Probable won't help but have you plugged your lappy in 2 see if there are any fault codes or anything else that the software might be able 2 pin point?

I'll make it there mate - I did say today or tomorrow, and I'm working on it fella!!! lol

My concern is that he will need to put this in series with the coil, not just in series with the tacho.

I am not sure what effect this will have on his secondary voltage output (especially seeing as he runs on gas), let alone what effect it will have on the tacho input to the auto.
