Well i am having a few issues with trying to get uberdata to lean out and run richer at different spots on the map.

Right now 0-10 psi is getting 11.2-11.9 afr

But at idle its runner 18 - 21+ afr

and when just cruising around its getting 10-12 AFR

So, we leaned out some of the vacuum map and i got it to run around 14.5-15.1 crusing around in vacuum. BUT my problem is when i shift, it spikes LEAN.

how do you go about correcting this problem?

running 450cc injectors, uberdata 1.66, 42psi on the fpr.

would tps enrich help my problem?

 

When you decelerate or let off the gas no more fuel is being dumped in the engine. The wideband will pick up this non-exisitant fuel and display lean. EVERY wideband does this when you shift or decelerate. It's normal
