How many of you using 550/1300 have changed the
Sec Transition Parameter from 1.5 to 0.98?

I use :

Fr Primary: 100 0.00
Sec 0.04
Rear 100 0
Sec` 0.04

550 Primaries
1300 Secondaries

40% transition
0.98 (instead of the stock 1.5)

I changed the 1.5 to .98 months back after seeing it on a forum and at the time it seemed to help.

Anyone notice any differences?

I get seamless transition with the 550/1300 injectors running stock parameters under the injector table but upped values for injector overlap ... runs much better with these settings.

7 3
7 vs. 2
3 1

As viewed under settings5 on the datalogit.

 

try this again ...

7 vs. 3
7 vs. 2
3 vs. 1

and 0.2 lag adjustment for the 1300's

 

Ok, I've never really understood these two settings, so can someone give me a quick explanation? Afterwards, why change? I'm running the stock 1.5 and 3,2,1 setting and the car is running great. What is the benefit?

is this all adjustable from the commander or do i have to use the datalogit?

i havent been in my car for months but i dont remember a transition setting..

car is in the shop with 1300c's being installed after a rebuild..

i have a pfc/commander with a walbro fuel pump.. 550's and 1300's and a whole mess of other stuff.. thanks

 

These are settings that are not available for adjustment via the Commander, IIRC.
