I've been thinking of tuning my car / VE table in Open loop just to be able to get the A/F I want at diff situations ex. lean crusie. My WB shows 14.3 at cruise now in closed loop.....

I know one way is to raise "min temp to closed loop" but then I always will be in Open loop.

What happens if I set MAX BLM value to 129 and then lower my VE table at cruise to get a higher A/F value? This way you could force the A/F to be leaner?

Welcome back from your holiday. The $8D mask has a lean cruise high way mode built in. Just need to enable it. Look at and after location L8480.

Thx RBob!

Will go $58 real soon.

I just tuned my new engine with 8D code first because I'm used to 8D, and I did not want to start with new code and new engine at the same time...... now its time to go $58.......

I want to go a little leaner when I drive on the highway so that my milage will be better, gasoline here is like 5.5$/gallon.

So would locking BLM or change enable temp for closed loop? any pros or cons of them that makes one better?

My holliday was rain,rain,rain according to Craig the weather over there is hot, hot, hot
