Sc14 to buick and e85

[vlad01]

not that I am aware of?

Pretty sure someone of here made a launch control work using the rev limiter?

Yeah, you need one of VL400s ignition module. It has its own spark cut functionality in it. http://pcmhacking.net/forums/viewtopic.php?f=11&t=2913

You'll need to check availability with VL400.

You can see it in action in Holden202T's latest log post: http://pcmhacking.net/forums/viewtopic. ... 780#p42565

You can see at 6:07 the rpm goes ripply with spark cut at 3000 RPM, then boost psi (BPSI) starts rising and is at about 2-3 psi when the car starts moving. Much quicker to get to full boost.

Got a little side tracked this weekend building an air box as the s/c is making a hell of a racket now that I'm spinning faster. The wideband arrived on Friday, so I will finsh off the air is next weekend and and install it. Then I can get into the tuning.

Hopefully there is someone online who can help me. I have my mtx wideband installed and wired up. Problem is that the rading on the gauge does not match the logged reading in tuner pro. I have the gauge set to e85 and I am using the e85 2 bar adx. Any ideas?

At 9.0 afr on the gauge I get around 2.2 v on pin d8. So, I think the analog out put off the gauge is right, just that tunepro is not logging it right. Had a look at the adx and changed the values under wideband o2, but it didn't affect the logging in tuner pro, cand anyone point me I the right direction?

More info- volts = 2.38, gauge reads 9.5 afr and tuner pro reads 14.3 afr.

The 0V AFR and 5V AFR settings for 12P need to be setup in your bin before you get any logs. The ADX calc is always left at X/10.

More info here .. http://pcmhacking.net/forums/viewtopic.php?f=10&t=3583. Just note that the video relates to bins other than 12P so the adjustment process is slightly different.

Thanks. That fixed it.

What is an acceptable range for afr? Should it always be under 9.8 under acceleration or is it ok to be a little bit lean?

have a look at the open loop air fuel ratio table, it will tell you what the tune is commanding at what loads!
