Needed: Tach Generator or Boost Module

I'm sure you checked this already. however what's the resistance from your battery  neg terminal to your "ground" ? I remember once when i did a civic, i picked a bad ground, with a resistance of 100ohms and that totally messed up the tach learning..

From My what my DEI rep he told me ... Was to change grounds and that totally fixed the problem. he said should be less then 10 ohms.

I think i have a tach booster in my tool box from doing a preditor starter let me check tommrow when i'm at work.

silvercivicsir: Ground for the system is less than 10 ohms. I beefed up the ground also on the battery for the vehicle to see if this would help and it didn't.

mo12v : Where would this mount on a diesel engine ?

Here's the pic of the alternator that I used for the tach signal. Any thing seem wrong here ? Just asking those who know VW diesels

Hey Mike,

The problem with the VW is that the alternator doesn't start charging until the car reaches about 1000 rpm's. The diesel doesn't rev any higher ( in most cases ) above this unless at driving speeds. The main problem is that I can get the remote start to learn the tach ( no problems here ), it just that after the car has sat for any period of time, the tach signal isn't strong enough for the RS to pick up because the alternator isn't outputting a strong enough signal becuase it doesn't charge under 1000 rpm's. I'm hoping with the tach amplifier, the small signal that is being output to the RS will get amplified enough that the tach is recognized when remote start sequence is activated.

Just for review, what happens is the car is placed into ready mode after it has been parked from driving....... ready for remote start for the next day. Customer presses the start button and car turns over crank and then dies right away ( within a second or 2 ) . RS tries 3 times and then has a no start error. Now here's the kick in the pants............. if the car is placed into ready mode and you try to remote start the vehicle right after driving it ( do not let it sit for any period of time ) , it works fine........ no problems at all. Catches in the first try and runs through the 15 minutte cycle the way it's suppose to.
