Zerep Posted April 7, 2018 Report Share Posted April 7, 2018 I have Link ST185 pnp ecu and i can't get my car to stay on.The mr2 has ID2000 injectors and oem 3sgte gen4 coils & trigger sensors.I changed injector dead time values to to the values injector dynamics have on their website for 43.5 fuel pressure.Wondering if any could help me i am new at this MR2 3SGTE 4-7-18.pclr Log 2018-04-7 MR2.llg Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 8, 2018 Report Share Posted April 8, 2018 A couple of thoughts: ID2000's are high impedance but the car had low imp std, did you remove the injector ballast resistor? Your map has a 5D ignition table turned on with 50deg retard in it and then 65 deg advance in the main ignition table? What is that about? As soon as the engine starts to make vacuum it will move out of those highly advanced cells and stall... I suggest you turn the 4D and 5D tables off and put some normal numbers in your main table. There are trigger errors counting up. I see you have set 36-2 on crank - are you sure the cam only has a single tooth? Can you do a Triggerscope so we can check what the problem is here. Have you done an ignition(coil) test and synced the base timing? Just for future reference - your log doesnt have many channels recorded, next time hit the "Add all" button at the bottom of the logging setup screen so we get more complete data.

Zerep Posted April 8, 2018 Author Report Share Posted April 8, 2018 1. Yes i removed the injector ballast resistor. 2. I switched the 4D and 5D tables off changed the main ignition table values to the ST185 ignition values. 3. Yes the cam has a single tooth and i attached trigger scope log below. 4.All four coils spark and i also re-checked the base timing with a timing light.

Simon Posted April 8, 2018 Report Share Posted April 8, 2018 So you have it that the engine bursts and then dies? Quote Link to comment Share on other sites More sharing options...
Zerep Posted April 9, 2018 Author Report Share Posted April 9, 2018 Yes it turns on for couple seconds and then it shuts off. Stay on if i give it gas Quote Link to comment Share on other sites More sharing options...
cj Posted April 9, 2018 Report Share Posted April 9, 2018 can we get an updated pclr after the changes Adam suggested, and log of it starting and failing, then starting and staying on as you give it gas - with the additional logging paramters? Its probably not the cause of this particualr problem, but your IAT is reading -23 deg C but your ECT is 14C. Id guess at least one of these sensors is running the wrong calibration. Are these both the factory toyota sensors? Quote Link to comment Share on other sites More sharing options...
Zerep Posted April 10, 2018 Author Report Share Posted April 10, 2018 Thank you for the help but I did a compression test and one cylinder did not have any compression so going to fix that problem. Quote Link to comment Share on other sites More sharing options...
Zerep Posted August 6, 2018 Author Report Share Posted August 6, 2018 I fix the issue i had on the car but now the car is rich and it doesn't want to start with fuel pump connected.It only stays on when i prime fuel pump before turning on and disconnect the fuel pump.Could some help me with this issue.I also added log file Log 2018-08-5 8;26;39 pm.llg Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 6, 2018 Report Share Posted August 6, 2018 Its a bit hard to tell without a copy of your current tune file but if you think there is too much fuel the first step would be to reduce the master fuel setting. Quote Link to comment Share on other sites More sharing options...
Zerep Posted August 6, 2018 Author Report Share Posted August 6, 2018 Lower the master fuel like you said and it turn on with fuel pump connected.Thank you Adamw,Simon and CJ for helping me out.I post if i have any other problem Quote Link to comment Share on other sites More sharing options...
Zerep Posted September 13, 2018 Author Report Share Posted September 13, 2018 Having another issue AFR stays around 11 and when I lower fuel table numbers it goes straight to 19 afr. 2018-09-13 3sgte.pclr 2018-09-13 3sgte log.llg Quote Link to comment Share on other sites More sharing options...
cj Posted September 13, 2018 Report Share Posted September 13, 2018 I think youve got a wiring problem with your lambda sensor or a massive exhaust leak near the sensor, or if youve got a programmable sensor like an LC1 then you've got it programmed wrong calculating back to work out what your received voltage will be to give those readings, the 0.78 ish lambda number is 0.7 ish volt, then it jumps straight to 1.33 ish lambda which is about 4.7-4.8 volt. My money is on there being a voltage offset of about 0.2 volt because of wiring, and the lambda sensor output jumping from what should be 0.5v (min) straight to 4.5v (max). Your injector pulse width doesnt change between when its reporting 0.78lambda and when it reports 1.32 lambda so its not registering actual fuelling changes.

Zerep Posted September 23, 2018 Author Report Share Posted September 23, 2018 Yea it was wideband issue gauge had something burnt.Bought new wideband and the readings match and they change when I lower or raise the fuel. Quote Link to comment Share on other sites More sharing options...
Zerep Posted September 23, 2018 Author Report Share Posted September 23, 2018 Can I use the oem mr2 knock sensor.If I can how can I set it up Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 24, 2018 Report Share Posted September 24, 2018 The stock knock sensor is connected if you want to give it a try. I dont know the ST185 well but most of the Toyota's from that era used a single wire resonant frequency sensor that is not particularly useful on a modified engine.

Zerep Posted September 24, 2018 Author Report Share Posted September 24, 2018 I have 3 Knock sensor available.Using the oem 3sgte ST215 resonant frequency sensor and I have a GM knock sensor not installed last one is a 2 wire non-resonant knock sensor.Do I have to turn on knock mode for the link to read the 3sgte ST215 knock sensor.

Yes, of course you will need to turn it on (On - Knk Internal). You will also need to set a relevant frequency and gains etc. Quote Link to comment Share on other sites More sharing options...
