Volcom86

@Adamw @Adamwyes it does have a gauge. I will see if I can get the part number/photo MFG: 30-4110 SKU: 146 Which seems to use the LSU 4.9 wideband sensor Unfortunately it does not match the dyno lambda. Mine shows way richer AFR Example mine reads under 10.0 AFR and on dyno wideband it is leaner at 11.4 at full pull just where it should be! It use to read closer to the tune AFR and over time it got richer and richer but the car still pulled fine and hard and did not break up under boost which I thought it was strange because if it was this rich it would break up under boost! Hence why I wanted to get it checked and put back on the dyno. They told me it could be the gauge or sensor or earth connection having issues. I was trying to trouble shoot the ECU map file just to see if there is anything that sticks out and noticed these settings were like that mind you the current tuner has not touch this setting and it was presented by another previous tuner. This is the gauge I have. I also believe the wideband sensor has been changed somewhere along the lines.

I came across an issue that my AEM UEGO gauge is reading rich at 10.0AFR when under load on the dyno. Their Bosch Sensor reads 12.0 AFR at same load and RPM My questions is I just noticed my ECU settings are set up as a Zeitronix ZT 3 when my gauge is a AEM Uego... Would this possibly be an issue or have some side effects?

The Ethanol content is displaying at 0% @Adamw Thanks

Thank you @Adamw I tried it out last night but for some reason it didn't work. Thank you

I have one last question. What am I doing wrong here... I am trying to get my Ethanol % showing up and I have follow this little tutorial https://1drv.ms/u/s!AiYbYlZQuRHPtGpksumYRqo5cH7A?e=L0nxEN but I guess I am still doing it wrong. I have attached the ECU file as well as the PLEX configuration.

@Adamw you are a absolute gun mate!!! THANK YOU!!! IT BLOODY WORKS... I did an Indian dance when it powered up and worked haha. Thank you so much I really appreciate it Adam Hope all is well take care Ps i looked at it and I am not sure what I was thinking

@Adamw Attached Plex Config Thank you Plex SDM-500 Link Config.pdc

Thank you @Adamwfor looking into it. Unfortunately I haven't got photos of it atm as I have closed it all off. Once I get to it I will get you some photos Adam. What I did was purchased the Link 5 pin connector and made my own Can-Bus. I connected the Number 2 CAN wires from the Plex device and connected it to the Link Ecu CAN Number 1 connection directly with the twisted wires the Plex comes with. Could this be the issue? Could the other issue be that I am using CAN2 from the Plex device into CAN1 on the link side? As you know the Plex Dash comes with CAN1 & CAN2. I connected the Plex to the ignition 12v and Ground to the cigarette switch ground so it turns on when the Ecu comes on. Thanks again for any input as this sure has me going nuts spent almost the whole wknd playing with this with no luck.

Hey all, I am having issues viewing data from the ECU CAN1 to the Plex SDM-500 Dash. I have updated the Plex to the latest firmware so it is all up to date The ECU is seeing the can port connected however the dash display is not getting any data. Any feedback would be greatly appreciated. Thank you Attached files for reference

Thank you @Adamw really appreciate your help Thank you

Hey Guys, Looking at getting my self a Plex SDM 500 - Display & Logger.. Couple of newbie questions will it work with the G4+ - anyone else running one? Also what connector do I need to connect the Plex can-bus to the Links can-bus so I can plug it in Links ecu (photo attached for reference) Thank you in advance

Ask the tuner for the original file map he should have it saved on his laptop. If he is being 100% truthful he would not have an issue sharing it

Would there be a reason as to why going from 60% Ethanol where it was tuned. To filling up with more ethanol making the mix 69% - 70% make my AFR/lambda read richer? Example E60% Lambda target on full load .790 (Lambda actual .785 very close from target) after putting more Ethanol at the petrol station increasing my Ethanol content to 70% Example E70% Lambda target on full load .790 (Lambda actual .750) This is what I am seeing is this normal? Thank you for any feedback

@Adamw Did some testing this morning and BOOM the idle issues are gone! Now I do have an issues with Idle being at 11AFR not targeted at 14.7AFR Adjusted the The min Eff PW and the CLL RPM low lockout at 1,600RPM https://www.dropbox.com/s/ojlb6va0vd9hirn/111.llg?dl=0 The CLL seems to be out more then before. One thing is fixed then other issues arrive Thank you

Thank you @Adamw I will give it a try and report back. As always I appreciate your feedback and help so thank you!

Thanks Adamw, I will give that a go... My Injectors are ID 1,700x My tuner has tuned the car with a different closed loop gain this was the original as I had issues with idle AFR at idle hunting however the idle was stable And these are the new tweaked settings So I am not sure if this has any affect on the idle issue. The other thing I Should point out is this is the first time me really trying this on 98 petrol could this effect anything coming from e85 ??

Thank you!

I am having a strange issue that was not present till now. My idle will drop under my target idle value and it will stall at times. I am noticing this for example when I am reversing parking when I need to be gentle on the accelerator and just give it lite blips. Sometimes when I am pulling up to a set of traffic lights. Does not happen all the time. Any idea what is making this? Attached log and map https://www.dropbox.com/s/v46290ewszho9vd/Idle and cruise .llg?dl=0 2005 STi with cable throttle body I appreciate any feedback thank you.

Thank you all

This will be a silly question however If Close Loop is pulling out -8% in some areas for example do I add fuel in the fuel table cells or take fuel out in those fuel table cells Thank you

Could it be because the AFR sensor is so far away in the mid section of the exhaust? So it a delay factor and not a actual lean spike

I have taken the solenoids out gave them a good clean ans swapped them around and success. Back where they are in sync. Thanks for pointing that out remski2 Still seeing the random lean spike. I don't understand it

Yes, indeed thank you pointing that out it looks like the solenoid is lazy. I will swap them around and see if bank 2 will repeat the problem Thanks,

Hey Adam, Hope all is well. I finally got to go do some testing. I changed added some Accel Enrichment above 4,000RPM am I perhaps not giving it enough? Attached log file. https://www.dropbox.com/s/s8x6r4v3upesly2/test 7.6.2020.llg?dl=0 Injectors are 1,700 ID's 04 MY05 STi with standard drive by cable throttle body I should also mention that my AFR sensor is in the middle part of the exhaust past the dumpipe section where it meets the middle section Thank you for any feedback

Thanks for the Input again Adamw... I forgot to ask if the lean spike in the log could possibly be coursed by CLL rate down settings impacting this? Thanks again for your feedback I really appreciate it. Cheers,
