I did another pull on map 3. Fuel pressure would drop to around 6 and jb4 would reset to map 0.

Here are 2 logs.

Map 2 fuel pressure dropped.
Map 2 fuel pressure all I saw was go down to 9. (Disabled throttle controler and ran better)

I've never had any issues until I recently installed the EWG wires and throttle controller. Installed them at the same time.

Not sure if the throttle controler is causing an issue?

Anything to adjust?

[Terry @ BMS]

Makes sense. EWG connectors allow increased boost. More boost puts more stress on your fuel pumps. So must just be a factory weakness for your specific car. Unfortunately it's not something I can fix for you via software. Options bit5 would disable EWG if needed.

Thank for the response terry.
It ran fine until I upped it to FF 60 then FF 55.
Default settings of FF 50 I didn't seem to have any issues. Should I revert back to FF 50 and give it a try? or is that the same as disabling the EWG wires.

[Terry @ BMS]

You can play around with whatever settings you'd like, and monitor FP_H in logs to see what effect they are having on your specific issue.

Thought of something to try and loaded it in v17_t3 firmware just now. Load and evaluate if it makes any difference. Also, let me know what date you received the JB4 as there were variances in the JB4 boot up firmware that may explain the difference.
Older systems had a small extra delay.

Hey Terry, thanks for your earlier reply. I haven't been able to get solid logs without bit5 enabled after installing the EWG connectors, getting 2564/2568 every start, having to clear and then the car runs fine after a restart. I've quadruple checked my wires and even switched connectors but the problem comes back. Tried the 17_3 FW and still the same result. My JB4 was purchased September 2018 and the Stinger was mfg April 2018, USA GT1.

Try swapping out the 2580 chip for a new one. Email in your address and we can send you one.

I'm waiting for my new chip (thanks Terry) but if you just start the car, shut it off, and then on again, everything works right and no codes. Takes about 10 seconds. That's how I've been dealing with it for the past few days.

It also might work to press the start button twice with no brake on (so you get it into accessory mode) and wait a few seconds before starting the car. But I haven't tried that yet.

[Terry @ BMS]

Did chip resolve issue? Another customer said a new board resolved his. The new board has the new 2580 also. So I'm thinking that is all that is required.

[sym]

The new 2580 chip did the trick.

I also changed spark plugs yesterday so once the weather is good I will send some logs your way.

[Terry @ BMS]

OK good to hear, we'll get updated 2580 chips out to anyone with unresolved startup EWG codes that clear once ignition is on.

[wardyl36]

So I just installed the ewg wires and input the settings. I have attached a photo of the inputs used and I'm getting a code 2564, did I put something in wrong?
Thanks
Warren

[Terry @ BMS]

Usually fault codes mean a wire is in wrong or mixed up. People tend to mix up the purple wires we've noticed for some reason.

[wardyl36]

All wiring was in correct locations. Any thoughts what else I could be looking at? I just uploaded firmware 17.5 could being on the older one be the issue?
Thanks
Warren

[Terry @ BMS]

Sure older firmware could be an issue. If the codes clear and it runs normally until next restart could be old 2580 firmware we can help you with. Could be a loose or damaged wire in the EWG connector itself, like if a jumper wire pulled out, etc.

[wardyl36]

I started car up again and didnt have any codes after uploading new firmware. Could it be an issue with the 2580 chip? I'll have to check the connector, they seemed pretty solid when I installed them.. i cant recall when i purchased the jb4, I'm thinking it was November of 2019. Is there a way to check the date?

[neonland]

I just installed secondaries and a *** back. I have the ewg wires but set to default. I had an instance today where my car went limp and when I checked jb4 the map had dropped from 4 to 0.

I places it back on 4 and did a few. Short runs and it looks like I'm getting close to overboost in a few instances by about 1-2 psi.

Honestly I don't mind the extra boost but don't want it reporting it to ecu 14+psi.

What can or should I do?

Thanks

Last safety = 3 is fuel pressure dropping. I'd drop down to map3 and evaluate. 14psi is a plausible factory target and what we've designed the EWG control around.

Well, if the codes aren't coming back, sounds like it's solved.

The new 2580 chip solved the issue with the CEL, thank you very much! Car is overboosting with defaults as you suspected based on the bit5 run so I'll play with the settings and get some logs.

[wardyl36]

Went for a ride, here is a log. Is it long enough or do I need to redo? I'm running map 2 currently, seemed to run well. Any thoughts on adjustments that can be tweaked?
Thanks for your help

Not much WOT here but seems OK from what I can see.

Here are some logs for ya. Lowered Duty Bias to 45 (rest default) and no more overboost - WMI with 99 octane.

[Terry @ BMS]

Looks pretty strong to me. You can lower additive if you want to get boost target down further.

[ChiTownStinger]

Those of you who are getting codes or strange performance, try getting a new 2580 chip from Terry. I got mine today and all my issues are resolved!! Car is running great now! Thank you Terry for all of your continued support!

[12listen4]

installed my ewg wires this weekend and now im getting check engine codes at each start up. went back and rechecked the wire positions and also removed and rechecked the pins on the ewg wires and every thing looks fine. was on firmware 17 and went back to 15 to see if that made a difference and it didnt. unlugged the ewg wires and everything is back to normal. Thoughts???
