Okay if I post my map would it be possible to make some tweaks? https://www.dropbox.com/scl/fi/99zr9qtqpodz6r46ezmz9/newspeedo1.pclr?rlkey=u1h8pssq16fhe5567y4xitzhe&dl=0

So the so the lambda is richer than gauage, I don't think I have the gauage ground wire to and actual sensor ground it is grounded to body. The O2 sensor sits at top of down pipe. The ECT ignition timing might be advancing because it was harder to start when my IACV was playing up, is it possible reaching max ignition?

When cols starting, hard acceleration/ full throttle the car is hesitant and bogs down, possible fuel related. Fine once about 60º+ can't seem to pin point any help appricated log attached. https://www.dropbox.com/scl/fi/hbwp6zkaxa14u4m19abhi/start-up.llg?rlkey=ulbqou1w22x4so1ds4t7nh2e6&dl=0 SUPRALINK 2JZGE-T SINGLE TURBO

Now worries I appricate all the help thanks,

no worries, i appricate the help. https://www.dropbox.com/scl/fi/hbwp6zkaxa14u4m19abhi/start-up.llg?rlkey=ulbqou1w22x4so1ds4t7nh2e6&dl=0 sorry this is my log, is there anything i can do with the minimum frequency to stop it jumping up so fast? its not a big deal tho

no worries, I do have a bit of a look but sometimes unsure where to start. I changed some settings offset to 0 multi to 0.98 max frequency to 400hz the speedo moves now and speed is pretty acurate but the need response seems abit slow? also, when i take off the needle jumps to about 20km/hr almost straight away then will start to move accurately as speed is increased, any idea what to check? https://www.dropbox.com/scl/fi/99zr9qtqpodz6r46ezmz9/newspeedo1.pclr?rlkey=u1h8pssq16fhe5567y4xitzhe&dl=0 new log file

I really don't know what these values should be I'll try that today tho and get back to you

I have a similar problem, my speedo was working fine, but i coudn't adjusted the speed through the G4 software. when trabeling 100km/hr speedo in car was showing 120km/hr, its out because of tyre change. So I've tired wirng up the speedo as per this post linked, using a aux input and digital but dosen't seem to work, when i start moving the speedo will move up to about 10km/hr and stay there until coming to a stop? on the G4 software AUX for speedo becomes green when moving, then turns of when stopped. anymore help would be great. this is my log file https://www.dropbox.com/scl/fi/z9axyr7mvv1ey4b3jz2z3/newspeedo.pclr?rlkey=y5y9f5kbiwiga20bo2odyj49n&dl=0 https://www.dropbox.com/scl/fi/dbzodpsn52jugjf2hwarf/screenshot.png?rlkey=rua4tw8akvwqdy1uokkbq99s1&dl=0

having issues with hesitation when trying to accelerate hard after changing gears when cold, or depressing the pedal fully. usually fine around 50 degrees celcius, feels like a fueling issue/cut, maybe over fueling? any help much appreciated. log attached 2JZGE-T jza80 log file https://www.dropbox.com/scl/fi/db9io8ka1zklos53jpukb/log-1.llg?rlkey=oqxszdia7wtqb70mtku1xtyxv&dl=0 map file https://www.dropbox.com/scl/fi/5u0lsth5zf3h8fvqqs0wp/map1.pclr?rlkey=kja0pti0i65bqfkaljutuz9d4&dl=0

tried your map and its fixed the issue. thanks so much!

Okay I'll try your modified map thanks, I wanted to see if it was IAT making the idle change as it got hotter, the IACV is aftermarket 2 wire With the idle table could you post a example image or what you mean. I'm a little unclear

Okay I'll try this thanks,

Still haven't figured this out just yet,

cant seem to figure out why my idle jumps around, rpm target is 990rpm, after letting off throttle, ususually falls slowly to about 1100rpm, stay there for a random amount of time them falls to 990rpm. Can be sitting there with no throttle movment and just up randomly to 1100rpm.

Hi guys thanks for the replies, so I was only getting 11.6v at the main relay input and battery was reading 12.6v, looks like some wiring between the main relay output and a fuse had cracked solder and slightly melted. I cut and re wired, all fixed. Thanks for the replies

No same reading as ecu

I am having the same issue on my supralink ecu, was there any fix ?

as of a few days ago my link ecu can gauge isnt reading properly, the voltage seems like the most noticeable incorrect reading but not sure if the other readings are. voltage on G4 software says 11.7v but at the battery it says 12.6. I have a few CAN errors achknowledge error, bit recessive error, error passive, bus warning. this post above, is almost exactly what is happening with mine, i thought i had changed some fuel settings because it was running very rich error.pclr

The dropp at ideal is fixed, only thing remaining is the irratic deceleration around 1800-1100rpm, seems to get worse after those idle adjustments

ill try these changes and see how it drives over the next week, thanks
