need something explained

Post by fleettech2252004 »

Good evening to all,,

I have an Auto X-ray EZ scan 6000 scanner, and when i run through the operational data, it doesn't have fuel trims,,, it shows Block Learn and Integrator.

Can someone enlighten me to these two items?

Just so you know,,,,,

Block Learn shows 140ish

Integrator flucuates 125-135

Thanks for your help

Block learn is long term. Integrator is short term. 128 is the ideal value. The 140 long term means it has to add fuel to maintain the mixture. The 125-135 short term means it's got it figured out. Although it can't add a whole lot more.
