Thanks for that info RE CAN wideband. I will look into the purchase of a new one. For now @Adamw attached is the log file of the cold start issues I was describing on the map you sent me above cold issue jacks 2jz v6.llgx

Thank you Ricardo and Adam Adam, I ran your map and captured a log for you to see. To my lay eyes and ears lambda looks better, significantly less throttle hesitation - especially when warmed up. When cold, hesitation/bogging on throttle is mega but idles find without any throttle input. Base timing set and right on the mark with timing light, idle about 8-900 steady. I did perform the calibration lock screen function and as I am using a distributor for crank and cam signals, rotated it to match the value that I input to the first box. Sorry about the confusion above - my MAP sensor is a 3 bar aeroflow sensor (AF 49-1552)-I used the data from the manual for the linear calibration found here AF49-1552.pdf (aeroflowperformance.com) My Fuel pressure reg is cheap and there is a restriction somewhere which means my base fuel pressure is 4 bar - but is stable. My wideband controller is AEM 30-4110. How does this new log look to you? running on jacks 2jz v6 thanks adam.llgx

While looking over the log myself I noticed that the closed loop wideband stoich wasn't active/set up. I quickly amended this with (guessed) settings, opened throttle plate with screw a little bit and smoothed some of the fuel 1 values to match predefined lambda targets and it runs alot better. I have a feeling that my master fuel is still too high given the fuel table values being so low. I also am not sure that my ignition control idle is working at all. All your advice is appreciated so I can feel confident to take it to the tuner! Attached is the amended map and the new log jacks 2jz pt 5.pclx rich issue with lambda control active.llgx

Prefix: I am not a tuner and am just trying to get the car drivable to take to a tuner. Background: 2JZ Na + T Large FFIM + 90mm TB - stock 2JZGTE TPS NO IACV - deleted New Bosch 731cc injectors @ 3bar Fuel pressure set to 4bar Fuel pump 12v mod - maintaining 4bar on FPR gauge Aeroflow MAP sensor - calibrated and appears correct Bosch UEGO wideband sensor through generic controller with linear calibration Ignition: 6 x yaris coils Trigger signal from distributor sensors Engine runs and idles, easy start without throttle - although rich Leans out under throttle and bogs down - the faster you stab the worse it is - maintaining the throttle seems to fix Likely an issue with my idle ignition I do not appear to have an idle ignition control table even with idle ignition control switched on either(why?). I have also had to turn master fuel down to 5ms for it to idle (still rich). Likely many other things wrong with my map as well (please help). jacks 2jz pt 3.pclx throttle issue.llgx jacks 2jz pt 4.pclx

The circled component appears fried. Is this what you were referring to? Noting I am not an electronics tech, what is the best course of action if this would explain the symptoms? cheers. side note: considering I am not running any evap or vsv would there be any harm in bypassing mrel and activating 24 from switched ignition power?

Hello I have a TS2jz v1.2 ECU with a factory 2JZ-GE harness Initially I didn’t realise it had a JZX100 map loaded and when I connected the ECU, it powered up and the fuel pump ran, and continued to run until I pulled the EFI main relay. I then benched the ECU, loaded 2JZ base map from the default files. I am now not getting power to the EFI main relay at all. I have: checked the relay and fuses, verified there is constant power to ECU pin 33, verified there is switched power to pin 1, there is no power from MREL pin 24 to the EFI main relay. looking at the diagram it doesn’t look like there is anything else required for mrel to activate the relay? if I jump pin 3&5 of the efi main relay, the fuel pump turns and the ECU powers up. The issue appears to be with MRel output pin 24. any ideas on what to do next? Cheers
