Hello guys little background on the car 1998 Acura El with b16a2 running;
t3/t4 turbo, walbro 255, tial 38mm Wastegate with 7psi spring combination running stock head/block except for arp head studs. Tuning with crome dealer on a p72 obd1 ecu, running AEM wideband, prosport boost guage paired with prosport electric oil pressure guage.

Now to the question where should my AFR be at Vtec Engagement here's a recent datalog of the high cam. Thanks in advance !

I understand where my AFR should be while in boost but what about the vaccum of high cam map.

 

You're running lean. 11-11.8 should be your target.

 

Thanks for the reply! So as soon as I get onto the high cam map I should be in the 11.8's? I will change my target afr's and go from there!

 

Roughly. Your VTEC kicks in about 53-5400? Depending on your boost pressure. What are you pushing? If I'm reading you pic correctly up there, not very much. So by 'TEC kick, 11.8 is a start, working to about 11.5-11.0 up top.

 

Getting better than!
​​​​​I'm only pushing 7PSI no idea how much HP sadly hasn't seen a dyno yet. Definitely feels better throughout the pull since I added some fuel.

 

Good deal! By full boost, you should be no leaner than 11.8. You can fatten it up a bit more to about 11.5-11.2 but I wouldn't really go too much more than that.

 

Thanks for your help!! Me and the car appreciate greatly 😁 One other thing, if the datalog doesn't log certain values it's just because I'm so far off?

 

Glad to assist! Unfortunately, I'm not overly (or any) versed in crome so, i'm not sure about that..

 

Understandable crome has been great to me but can't wait to upgrade. What would this mean on a different program?

 

For mine (Neptune), it's just not tracing those areas..

 

Okay I'll keep working at it! I only ask because when I was overly lean it wouldn't trace those areas at all. Maybe I just answered my own question though haha happy boosting!!
