when my rpm goes to 2k rpm it starts bucking like crazy. once its pass that its fine. another thing is, when i change gear and step on the gas again it satarts bucking. what can be the problem. i tried going as rich as -34% and as lean as 44% at 2k but it still does it.

 

bump for friend

 

Try richening the 2K rpm area a bit more than -34%. The SMCplus has the added advantage of being adjustable which allows you to custom tailor it to your specific application.

We will be releasing a new device called the DBS soon to help eliminate some setups, including VAFC hack users, that have slight hesistation at low throttle inputs. We have some HT users that are already road testing the DBS prototypes!

 

ok now 2k is fine but 3k is doing it now. when it boggs does that mean its rich or lean. its really bad when it boggs. its like a rev cut.

 

wtf? You sound like an info commercial

Did you decide to clip the MINIMUM and maximum voltage of the map? If you did, this wouldnt be good for idling gas milage, heh. BTW if you need to kno the voltage at which the ecu cuts fuel, IM me. I foudn the code in the rom that cuts fuel for extreme vacuum

 

if i cant tune this **** out im going with your chip uberteg. im still looking around for a obd1 ecu and a converter harness.

 

you'll be able to tune it. Goto pep boys and buy an autoemeter a/f guage for $50, it will help you out a ton. Gives u a fairly good idea whats up

It would be a shame for the smc to pass thru so many hands I sold it to you cheap cuz i had no use for it now that i had boost hcips

 

i do have the a/f gauge but kinda hard to tell where its at. just at the 3k thats the only problem.
