Rb26 trigger settings for cranking

[turbodailydan]

I’m running a ross 12-1 trigger setup on my rb26 and have issues with cranking time. She doesn’t fire up straight away and cranks over for approx 5 seconds before firing up. It’s a 12 tooth crank trigger and 1 indent cam trigger. Ross have since changed the design of the cam trigger to a tooth rather than indent, not sure if this would make any difference?

Can you do a PC log of it cranking and starting.

Normally it’s the crank to sensor clearance to get it the pick up straight away it’s delayed.

try adjust the clearance to 1mm max.i have gone up to 0.8mm max.hope this will help.

In that log it takes about 1.5 seconds to "sync" (it wont spark until it has synced), it then takes another 1 second until it is running.  So 2.5 seconds doesnt sound too bad to me.  You should be able to reduce the time to start after it has synced by tuning the starting settings but the initial time to sync may not be able to be improved much assuming that is about as bad as it gets.  If you have a log where it needs to crank significantly longer then we can take a look if it is the pre sync or post sync that is the problem.

Ok thanks guys I will get another log of it when it takes longer to fire up. That was probably not the best example 

 

also im unable to adjust the height of the sensors as they are preset in the mounting brackets that they are supplied with (ross performance)
