All the gear no idea

Edit to this - I had the switch routed from Di16+ to Di16- Im guessing that due to this configuration it is waiting for a pulse or change to activate it. I have wired the switch to 12v live and fed back into the negative connection on the ecu (di16-) and it works fine and detects from a powerup situation.

This morning i have switched the boost solnoid to INJ 7. Seems to work fine now with no issues in both static and from an engine running perspective. Another issue i seem to have is when i first power the ECU up, it doesnt register an input on DI16. (I have a 3 position rotary traction switch on DI14,15,16) But if i rotate the switch to input on DI15 (when the cars powered up) it will then register active on DI15, and then i flick it back do DI16 it will also then show active. It just wont show it as active if it is being suppled 12v on that input from powerup. Anything im missing on that one? Thanks

The boost solnoid currently is fed from a 12v ign switch feed. Which is what is so strange. The voltage doesnt differ and isnt 12v, but the ecu for some reason is registering it as so. I will try an inj or ign pin for the boost solnoid and see if that makes a difference.

Hi Adam, So. i checked all the wiring, and when the IGN switch is switched off and the 12v drops out as you would expect. I did however unplug the Boost solnoid which is grounded through AUX 4 (fed off 12v ign sw live). When this is unplugged, the ecu shuts down fine from a running condition. When plugged in, the ecu doesnt power down using the ECU power hold function and displays IGN input on. But i have tested the voltage on the IGN live to the ecu upon power down, it is exactly the same voltage when the engine has been running vs when the ign has just been switched on and off (1.19V). So i am unsure of what to do next, as there isnt 12V on IGN SW even though the ecu is showing there is. Also connected the boost solnoid back to 12v switch live. But pulled the wire on AUX 4 (boost control) out of the ecu and the ecu hold power works fine both engine running and not running. Any thoughts on this? Thanks Andy

Hi All. Having an issue with my ECU hold power. If i power the car on without starting the engine, and turn off. The ecu power hold works fine and shuts off after the delay timer has finished. When the engines running and i shut it off, the IGN SW goes off, and can be seen going off, then a couple of seconds later the ECU detects it back on. But the key is now out of the ignition so has no voltage to it, so im unsure why it works when the engine isnt running, but not when the engine is running. Currently i am having to turn the IGN back on and off again after the car has stopped to get it to power down correctly. Please see attached log. Thanks Andy Log 2024-03-3 6;29;12 pm - ECU hold power not working.zip

So, it is now much happier and revs all the way up now. I have started to see if i can control the boost solanoid (its a 4 port) and intoduce more than 8psi of boost (wastegate spring pressure). It seems to be activating some ignition retard, and for the life of me i cannot figure out what is doing it. It is like a limit cut activating and it stops the engine. Ive scanned through all the ignition adjustment tables that i can find but none seem to be causing it. Its causing it to retard by around 5 degrees. PS i know i have some boost creep issues. Which i have narroed down to my wastegate diaphrams sticking. Ive atached the Log file from todays runnings. Thanks for your patience. Andy I believe ive just found the answer to my own Question. MAP limit table was set to 34.8 PSI. Ive upped the table and will give it a go tomorrow and see how i get on. Thanks Andy

I also didnt realise my AFRs were so far away from the target. I have tweaked the Map so they are running closer to the Target AFR and it Ran through to nearly 7000Rpm without stuttering. I will give it another test tomorrow and report back. I also adjusted my ignition delay from 40ms up to 130ms on the Crank trigger calibration and that seems to have got it staying rock solid at 10 degrees.

Ok. Ill clear out the trim tables. I maybe have the knock amplitude set too high. The Gain is up at 6 currently

Could you please take a quick look at this Log File. I did as you said before with the injectors and lambda. I had to modify the Dead times by around +0.08 which in turn has given me more fuel for the same number in the %fuel table. I am however struggling with even getting the car to rev out. It will free stand rev up to the rev limit of 7600 but when under load in 2nd, or 3rd gear, it will not go over 6000 rpm. If you keep your foot down even when its there, it does not sound happy at all, POPS and farts like somthing is restricting it and the revs dont increase. I have calibrated the ignition angle too but i will do it again as a precautionary measure. But even when changing the angle in the ignition table, it still doesnt want to rev. Thanks for your time. Andy

Ignore my last comment. Jve just done some research so ill play about with it. Thanks for pointing this out to me. It had me worried Cheers Andy

Is this Normal? Im guessing it should be disabled so that my AFRS dont go crazy on overrun. Or is it allowed to go that high during overrun? Thanks Andy

Hey Adam, Sorry for being so late in the reply. I have since sorted a couple of issues out including manifold gasket leaks. I have also fitted new wideband Bosch knock sensors to hopefully help with the tuning. I have one question which has me stumped (PS i will try what you suggested last time tomorrow with the deadtimes but i do not think this is the issue im having currently. I am doing a pull up to around 4-5k rpm but when i let off the throttle, under full vaccum the injectors seem to start at around 3% duty cycle, but then switch to 0% duty cycle after a couple of seconds, even though the fuel table is still requiesting around 78% fuel. Ive tried to attach the log but it is 9,000kb. Even compressed it is still over 4,000kb. Is there anyway to shorted the file size or take a snippet to upload? Cheers Andy Just realised if i delete the old log file off this thread it allows the upload of the new one. Heres the new one. Cheers Andy

Thanks for your time and reply. I will update the table with 0-145psi using cal 4. I did try this before like you have using the units 1000 KPA but then when i changed back to imperial psi on my units it reverted to 150psi not 145psi and i dont think it let me modify it (i could be wrong about modifying and ill give it another go. ill also give this fast idle lambda Target a go. I wont be able to test it tomorrow so i will feedback on friday. Ill record the log and upload it too. Many thanks Andy

Hi Adam, Thanks for the quick reply. The Injectors were bought brand new and were all sealed in individual packets so i can only assume they are genuine. The link MAP 4 bar sensor i bought brand new too so i am happy that is correct. It ties in right with my 8psi wastegate spring which i tested on the bench. The Fuel pressure sensor is a bosch multi sensor. It does fuel temp and pressure 0261230340. And im pretty sure its 1000kpa sensor (0-145 psi) but its down as 150psi. I will add the accel enrichment off the supralink file and also add the fuel related to the fuel pressure. Ill also order some bosch wideband knock sensors. I also had to retard the ignition by 7 degrees for it to be zeroed when froze at 10 degrees. Is this somthing to be concerned about or just normal? Thanks Andy

Hi Guys, Just some info on what im running. Link Thunder ECU, 99 oct pump gas. Bosch 4.9 Wideband Engine is a 2jz gte, running ign1a Coils, ID1050x injectors, stock toyota knock sensors. All sensors are fairly new and less than 150 miles on them and less than 2 hours drive time. So my fuel table values seem very high and are at nearly 150 for WOT pulls. My wideband seems to also max out after a WOT at 148 for a period of a couple of seconds. I have borrowed a map off another member off here for igniton timing, and pulled 6 degrees across the board on the timing. The knock sensors are still being triggered. Does this look like background noise or am i suffering with knock. (running 8 psi boost, 10.5 AFR and 7 degrees of timing). If you dont mind casting your eye over a log i have done and also the Map file it would be greatly apprechiated. This is the first time ever doing any of this so please tell me anything i am missing as im always up for learning.
