96Evo4.5

you may be right, I'll talk to my tuner to see if he will need extra time to diagnose this issue. He was trying to suggest that i do that to take one less thing off his list of things that need to get done is a fairly tight time schedule. However it seems as tho i can not get this issue sorted myself.

there is no log, as the car does not run atm, due to the harsh over fueling environment. The tune is the same as the last one that i shared via cloud storage link, the streams position is just set to "none". I need to buy a new CAN link harness (ecu end) because of the constant pulling it out of the ecu and my pushing probes into the end, its become misshaped and damaged. My next test is im going to get a new CAN plug and then im going to put it into the CAN2 input on the ecu, see if the ecu will see that instead. Maybe there is something wrong with the Link CAN1 input on the ecu board. im rather underwhelmed with the CAN input, i read all these great things, but in the end mine requires much work to actually work. But for now Im just going to hook it up to the Analog input as thats easier, and more likely to work. Could you please direct me how to hook up via analog, and what i need to achieve this?

So I tried this last adjustment and still nothing. Im thinking of giving up on the CAN setup for right now, my time to figure this issue is quickly whittling away. How do I setup up to the Analog inputs on the Link? what do I need now for a harness and such to try and communicate with the Link via Analog.

Oh okay, i'll make that adjustment. hopefully this will fix my issue. when he said none i thought he meant like zero lol

I figured id share it just it case I had adjusted the tune as per what Vaughan had suggested, (change the ID from 1 to 0) the current tune reflects that. I dont use 1 drive much, so I hope the link works properly.

i cant upload either the tune or the data log, it says the file size was to large and was skipped. the tune is 434 kb and the data log is like 700kb anyways, the tune was loaded previously i do believe, i havent changed it, it was listed as "Devins tune" I cant run the car currently as the ecu has been disconnected and i was advised by my tuner to not start the car any further, as the over fueling could damage the rings. But i did get a small log from before i dont know if that would help or not,

They are low Z injectors. I just found out from my tuner that these injectors are horrendously notorious for being difficult to setup for proper idle. So I may have to just get him to set them up for me. Its only money right lol.

I tested from the white plug on the ecu side to the white plug on the wideband controller, it came back fine. 0. So I dont know whats going on why my ecu isn't reading the CAN lambda. Is there any other setting inside the aem controller that I need to change other then setting the CAN to ID1?

I havent tested the plug at the aem gauge yet. That is my next step. But im gona go on a limb and say its likely okay. Yes I have some white wire I needed to add in to get the length I needed to reach the ecu. But I checked which aem wires I connected to and they are the correct wires.

So I tested both wires for continuity, from the ecu plug to the terminated plug, it was fine, I ran back and depinned the CAN L & CAN H wires from the LAMBDA harness and ran them straight into the terminated ecu harness. (Picture for example) i got nothing, didn't work no signal. I double checked my wires i was using from the lambda were correct and they were correct. I even switched the Can L and Can H wires around to see if perhaps I had wired them backwards, still nothing. I have the Green and black and white and black wires being used for the CAN. Does this apply to my situation? "Bus Termination All AEMnet/CAN networks must be terminated to have an equivalent of approximately 60 Ohms of resistance. Generally, this means a 120 Ohm resistor connected in parallel to AEMnet+/AEMnet- (or CANH/CANL) at both physical ends of the bus run. The X-Series controller does not have any internal termination and is intended to be connected to a pre-existing, properly terminated network. Please refer to the Bosch CAN2.0B specification for further detail." because i havent wired in any resistors, i wasnt aware that they were needed.

So I got the ecu out today, I dont have a plug that looks like that, this is what it looks like, please let me know if this is the issue. https://www.nzefi.com/product/nzefi-link-g4-g4-plug-ecu-can-cable/ This is a link to the cable I purchased.

I'm not sure, last I looked it said 2.434 for actual. i could load up my short log if you think that might shed some light? They are high Z as far as im aware, thats what they were listed as when I bought them, off an evo 8, and yes I still have the stock resistor ballasts in place. I have my master fuel set to 4ms and its still rich, like 12:8:1 but that is much leaner from previous when it was nearing 8:1

I would of done that already however i didn't, cause I'm having issues with my CAN sensor being read by the ecu, so I could give you a log but you couldn't see afr. It wants to idle at 900rpm but just stalls, when I apply 4% throttle its at like 1200rpm or so? And it sounds okay, its just rich beyond its wildest dreams.

I will double check it plug position today at some point, I do have a multimeter, but I've never used it for anything other then checking voltage lol, so I'm not actually sure what settings id need to test for continuity.

Id just like to start by saying thanks for the support here so far, Anyways, Ive got 1450cc FIC blueMax injectors. (of which im having a hard time finding any info on) I got them used and they never came with the data sheet. Ive tried numerous different dead time setting, and ive had a friend of mine who knows alot more about tuning then i do, look over the fueling and adjust for me. However I cannot get my car to idle anywhere even close to stoich, even with the master set to 4ms Im still running around 12.6:1 AFR. my fuel pressure is even lower then what stock would be, it runs about 40psi with a Aeromotive 340lph pump. Im hoping to get some bright ideas, as i dont even feel safe to idle a brand new engine with that rich of afr. It doesnt idle without the throttle pressed about 4% it just stalls. This is the tune that my friend helped me with. Devins adjustment tune.pclx
