delay accessory for cold starts

i am at a lost then, when i start with the key, it jumps to 1300-1500 RPM.   If i learn it at 1200RPM, it will not start on some occasions.

If i extend the crank time, can't use the tach, it will be voltage sense only.

Could it be a low vs high tach threshold setting issue? Does the unit you have give you the option (sometimes through a jumper or programming option) for tach threshold?Kenny

X 2 with offroadzj, you REALLY can't change crank time in tach mode?

There are no threshold option on my viper 5904.

Howie, per the manual

< lang=KO size=2 face=Futura-Book>< lang=KO size=2 face=Futura-Book>

3. Cranking Time

< size=2 face=Futura-Book>< size=2 face=Futura-Book>

• < lang=KO size=2 face=Futura-Book>< lang=KO size=2 face=Futura-Book>0.6/0.8/1.0/1.2/1.4/1.6/1.8/2.0/4.0 seconds: determines the starter output duration during

cranking for the ‘Voltage’ and the ‘Off’ Engine Checking Mode options

Unless you mean change the

14. Tach Mode Starter Release

1. Normal: the starter output will release normally during cranking (50% of the learned tachometervalue)2. Increase: the starter output will release later during cranking (at 35% of the learned tachometervalue)3. Decrease: the starter output will release sooner during cranking (at 35% of the learned tachometervalue)

If i go with Kennys suggestion plus option 2 of the tach mode starter release, 1200-1500 RPM,

1200+35% =1620 RPM to 1500+35%=2025RPM

14 was what I was getting at.
