How to adjust LT8 to not run so lean
 

When I am driving below 3000rpm with hardly any boost, My AEM UEGO Reads 10.3-11.2 ..too rich

When I start getting into boost it rises to about 12.6-13

When I floor it anything past 4000-5000 rpm it runs way lean at 13.6-13.8

Can someone help me fix my map?

show me your map first
is your afr guage wide band?
if its not. dont waste your time or anyone elses get a wide band.

The AEM unit is a wideband IIRC...

Ok then.
You need to use the load map to tune the points that are too rich.


So if your afr at 10HG is 11.0 afr you need to hold the engine at that load point. wait 2-3 seconds for afr to catch up and then in the load map go to 10hg and slowly reduce the number and watch the afr guage change(it wont be instant).

get it to 14-14.5:1(do this for 20,15,10,05HG).

then as you approach 0HG go to 12.7:1 and then as you go on boost bring the afr down to to 12:1 by 6psi. as you go more boost make it richer and so on.

You do this all by using the LOAD map.

how do pull my current map my tuner put on there so that ya'll can see it? I dont know the Microtech interface works. I have the cable to connect to it and the software.. Thanks for the help

youll have to manually go to each map and write it down. their is no way to download the map.

ok thanks
