AFR does look better. Only thing I noticed is you're still making some high boost over 5000 (17/18 psi). I'd drop that since you're just pumping heat at that point. Otherwise looks ok to me.

Default Fuel Wires Installed - AFR Reading staying at 25.5 - 07-07-2019, 09:43 AM

Hi Payam & Terry,

While I installed the WMI Kit, I’m hesitant to enable map 8. Reason being, I also installed the fuel wires and now my AFR reading(only for “AFR”, not AFR2) is at 25.5. AFR2 is normal (14.5-ish) at idle. The CEL on intermittently for first time. This only happened after installing the Fuel Wires. I saw a post to enable the future bit D0 and I did. The AFR unchanged at 25.5. Any idea what is causing this?

I would guess you either didn't get the posi-tap on the wire properly or have it on the wrong wire or pinned to the wrong pin of the DB25 connector of the JB4.

Possibly, but I triple checked pin position before installing(measure twice, cut once). I’ll go back and check posi-taps. Thank you!

You're doing the white wires on the O2s right?

Interesting. After 15 mins of casual driving my CEL went off . But AFR (#1) still at 25.5...under idle and a load? UGH

Any chance you have a DVOM and can do a continuity check between the posi-tap and the corresponding pin on the JB4 wire harness? If both have continuity it would also be interesting to see if they have @ the same resistance.

Oh and if you turn off FUD Bit 0 - does the same AFT issue occur?

Thanks for the DVOM meter suggestion, I will check. FUD bit0 was originally off and AFR (#1) had the bad reading, which didn’t change when I enabled the setting.

Do you know which side AFR is on (vs AFR2)?

There is the answer? I believe you need to turn on FUD0 OR the AFR reading will be inaccurate (Terry mentioned this on the v6 firmware notes I believe)

JB4_VR30_OBDII_6:

1) Added support for JB4 fuel control wires. To enable install wires to JB4 and set FutureUseD bit0 on. Once enabled you'll see "fuel enrichment" dynamically adjust in JB4 logs as it drives AFR up to the revised targets. Setting bit0 on WITHOUT the fuel wire will not negatively effect anything, but AFR readings in logs will not be accurate.

Thanks. I will continue to leave FUDbit 0 on. Do you know which side AFR(#1) and AFR2 is located?

Hey guys. Anybody else having this weird quirk on the meth gauge on the Jb4 app. When I’m at idle or parked, the meth gauge goes from 1-5. I verified the pump is not on while the gauge jumps up and down. Logs look proper and meth goes 100% at wot. It just started happening about a few weeks go and it’s just annoying. Below is a screenshot and a video link.

If all of those fail, just try and remove the positaps and move it up or down 1/4 of an inch. I had a buddy who installed his, almost similar issues than you. He removed it for a couple of weeks until I convinced him to put it back on. No issues since.

Could just be a glitch in the app. Are you on the most updated version of JB4 mobile?

Ok folks, WMI is working amazingly well...and I agree with Jrobohm, pulling like crazy! One caveat, I have some tweaking to do, as WMI is running 100% as low as 2200-3000 rpm. I’d prefer a ramp. After shutting down, looks like tubes may have emptied into inlets ( I hope not). Either way....I’m hooked on Meth ;-)

You can change the min max rpm or change at what psi the meth will start spraying Min Flow Boost. Default is 0, changed mine to 12.

Thanks. I setup at 10, based on Terry’s post to your thread a few weeks ago. I will tweak tomorrow.
