Who can help me. I would like to change only the secondary injectors volume to 1300cc ( prim 550cc ).What i must change in : Injectors Pulse Correction Value and Injectors Lag Time .
Thanks.

 

Someone !!!!!!

 

I have 1300cc injectors in my secondary positions. Tomorrow I can look at my injector pulse correction value and lag time value and reply. I have just purchased this car and I am not sure what injectors I have in or if they are set up right. I am assuming so,. because the person who had the car before me had AutoTech in cali tune the car. I hear they are decent tuners, although I think I am running very rich. I have posted me ING and INJ maps in another post if you want those.

 

Datalogit user ... just change your injector size to 1300 and adjust the injector overlap settings and lag setting to eliminate any lean stumbles at pri-sec injector transition. I run lag settings of 0.2 and overlap of 7,7,3.

You might try a search, this topic has been discussed to death.

 

Just to show you how engine specific these setting are:
I also am a datalogit user and have 1300 secondaries. To clean up my acceleration I set lag to -.02 and my overlaps are 3,2,1. Sad but true, these things are completely car specific.

 

Now my commander setting from srmotorsports is :

Fr-Pr 100% +0.00ms
Fr-Sc +0.00ms
Rr-Pr 100% +0.00ms
Fr-Sc +0.00ms
Q-Pr 550cc
Q-Sc 850cc

I must change 850cc to 1300cc and all (4) ms in 0.02ms?
what do you mean - overlap - ?
Thanks.

 

the manual tells you what you need to know... it is available on the forum in the maps and instructions section. you do not need a datalogit to make these changes. there was a thread about lag time for rc 1300 injectors a while back. i suggest you do a search. i don't see how these settings would be car specific as much as injector specific. i'm not sure what the end user would use to fine tune these injector settings anyway, perhaps someone could enlighten me?

 

BTW RC eng recommends .2-.3 for the lag setting for the 1300s, but you should still do the search. Lots of good info...
