Any idea's on the DI14?

P.S. ive added my file too, in case its needed to check things croydon finished map-danny modified.pclr

Hey guys. Ive played with the thunder ecu today and managed to work out how to log my wheel speeds etc but came across an issue im not sure of. In the setup ive selected di 11,12,13,14 as my wheel speeds which are running off a supra jza80 abs sensors. 3x of them show that the digital inputs are on and active except for di14! Even tho ive selected it as right front speed in the setup menu. I had the rear up in the air and rear speeds work fine and accurate. Just need to find out why my DI14 states "speed off" ? Any ideas to try? P.S. i had the fronts up in air and am getting no speed either (viewing live via logging and spinning wheels by hand). Tried even another set of sensors. These same wiring i used on my previous racelogic traction control unit with no issues with all 4x speeds reading, so not sure why this is different! EDIT: Added my file, please see next post

Brilliant Simon! Thank you. Lots to play with and test now, how good is this ecu!

Ok, awesome that worked, thank you. I was able to add the g force (and others) and have a look. One thing i noticed was my g force are out! Im getting 1g of lateral acceleration before i even start on the graph! Is there a calibrate g force sensors in the software somewhere? The numbers seem way too high!

Ive decided on the aem cd7, seems like a good bit of kit and very flexible. Im sure ill have plenty of questions once i start setting it up...

Hi. I am new to thunder ecu so bare with me please. I have went into the logging section, and have enabled paramaters i am interested to be logged via the ecu logging. After a race session, i download and save file before deleting ecu logs. Now when i go to view a specific log file, example, i want to view a log of my g-force, wheel speeds, i cannot see them in my parameter list or i cant figure out how to add them to the time plot to be able to view it! (I am trying to view my logged files offline if that matters?). What am i doing wrong? How do i view or put my speed parameter or g-force to my time plot? Also, my time plot shows say 3 items, engine speed, map, tps... how do i add say my afr to those 3 as well (i can see the afr in my parameter list, but i wsnt to add it to my plot). Im guessing its something simple, but i couldn't work it out last night. Thank you

Hey guys, I'm in the market to buy a data dash, since i want warnings, data displayed etc. Logging isnt so important as ill be logging everything with the thunder ecu, so if i need to see something i can always load up logging from the ecu. My main concern is suitability with the ecu I'm running... can anyone suggest or confirm which of the dashes they used that worked 100% with no issue's and can accept the links protocol? I want to make it a simple mod and something easy to understand (if that's possible lol). I dont want to buy something just to find out it doesnt support my ecu, or the data seen by the dash becomes odd and unreliable because it doesnt understand it etc. The main ones I'm liking is Aim Mxl2, aim mxs and the just released AEM cd-7. I like the new motecs like c125 even tho maybe a bit small? But am confused with all the features that need to be enabled to have the same capabilities as the aboves? . just confusing to someone like me.. Anyway... opinions and advises appreciated.

Adam, I have changed the settings to saturated on all 6x injectors, and replaced my dead ignition coil that i had(one of the coils died after only a few drives). Car started fine. Took her out for a quick spin and she rev'd nice and clean with no misfire/breakup whatsoever, so i am 100% sure the problem is fixed and that is all i changed, just need to get the tune and mapping right (runs lean up top) but i will update that as well once done. Yes, mistakes can be made and missed, but you guys were probably busy and in a rush so understandable, but appreciate all the help i got from you guys, maybe if you were to go through it the second time with more time/detail you would of picked it up. Im just glad i picked up on it and was able to solve it, i was starting to pull my hairs out of what i have left lol. Now to unleash the features of this ecu

Also, i think you will find that it went lean due to the breakup, which im suspecting was due to the injector setup?

Its running on e85 fuel so im hoping it didnt do any damage, and it was a quick hit only. I do have knock sensors x2 hooked up, but they have to be turned on and set up. I dont tune my car, i gave it to a popular tuner but he couldnt find my problem and gave the car back to me for me to go through the wiring as thats ehat he thought was the problem, so he didnt get to finish the tune. I dont know why he was using traditional fuel mode! Maybe its his preference. I will be going to a different tuner now after all these issues. Is 200kpa only 2bar/30psi ? Because the link when it says 20psi for example, you take away the absolute pressure 14.7psi and your only running 5.3psi, i dont know how you can set it up to just show the normal way without including the atmosphere pressure? 20deg on e85 is ok. Thanks for taking a look, did you find anything abnormal in the setup that would cause my ignigion breakup? Did the log show this breakup? Or did eveything look normal? Cheers

ok, link posted and I think that should work, please check and let me know if all good. I also have some success today, I went into the program and changed them all from peak n hold to saturated, and the amperage then became un-changeable so it was seen as 8A for peak and 0.1A for hold(this cannot be changed for saturated injectors). Stored to ecu and went for a quick drive. I gave it a hit and easily went to top rpm and boosted fine to about 20psi with NO ignition breakup or any ubnormal issues, I was extatic! finally thinking YES, found the problem, but then just as I backed off and was going to attempt another hit, it starts misfiring constantly even on idle and cruise. drove it back to garage and found my ignition coil no6 dead( no spark out of it). I did swap it to another 2 different cylinders and the misfire followed(wanted to be sure it was the coil), so now I have a dead coil that I got to replace before going out again to double check and make sure it is fixed, but I'm sure it is now since it was a major difference and you can tell straight away as soon as I gave it, I was just only able to give it once tho before the coil died. ive set the coil dwell to an 2.4 to 2.3 dwell as was told to do so. What I don't understand and am disappointed that my tuner didn't find this issue ( but neither did link ), obviously he played with the setting otherwise how did I end up with those mixed values??? Another issue is I downloaded that base map file from the links software, and I had a look and when you go to the FUEL>INJECTOR SETUP> injector setup it doesn't give you the "spanner" option to be even able to go in that section!? my question is, how do you get that section available? because after my tune, I am able to get in that section but not from the links base map! its as if you have to make it available by setting something up first? is this correct?

ok,thanks for the tip, I'm trying that now. https://we.tl/kZ5a9LueOI

Im trying to upload a pc log but file size too big, any tips how to do this?

Hey guys, weekend is coming and ill be able to do some pc logging for you to check out. In the mean time, ive been looking through my setup in the pclink and noticed something strange, and would like your input/opinion on it. Please see the image. I have bosch 1250cc high impendance 12ohm injectors and im told with high impendance it should be set at *saturated* drive mode? Now my one has all 6x as peak and hold and not only that, but the amperage on the peak and hold section on 2x (or 4x depending how you look at it) of the injectors are totally different! What will this do and could this be my issue? Much appreciated.

some logs with stock ignitor and with link ignitors, hope these help? thank you danny log.llg log with link ignitor.llg hi, some of these questions are beyond me, as I'm assuming my tuner should know them? injectors are bosch 1250cc top feed stainless steel e85 compatible injectors. 1st and 2nd gear I tried myself, the tuner I'm sure tried other gears? the dwell were at 1.4ms for stock ignitor but ive tried raising them to 2.4, once the link ignitor was on I also tried 2.4/2.5 coil dwell time. the traction control method that you mention I haven't tuched as I left those settings to be done by the tuner as I didn't feel confident in doing those, but ill have a look and try see if I can understand what numbers and info I need to put in there, any chance I can get a safe info on what numbers and what not I need in that section? thanks for your time, appreciate it.

From all the reports i got from the dyno operator and even i believe his name is ross honor from link? And link technical themselves Who was helping out me and the dyno operator could not fault any of the triggers while looking at the scope and data logs live as he was checking via remote link. I changed to the recommended ignitors and it made no difference. Coils and spark plugs changed. Dwell settings changed. Disabled all other functions like traction control and boost control, fuel pressure logs shows stable. Ill post my log when i get a chance. Cheers is it possible to check in the file that i posted to see if there are any limiters set? That i may have missed?

Yep, you guys have been a great help and much appreciated, couldnt have asked for a better team. We installed new 3x channel (2 of) link ignitors tonight (6 channel total). Again, car starts fine, runs and idles fine, low load fine, and once that boost starts coming up around the 10psi range, it starts having the exact same ignition/cylinder cutout, so it wasnt the ignitor that was the cause. What gets me is no other part of the wiring was tuched and looking at it all i cant seem to find any wiring problems. May need to start all over again... Oh the joys haha

I have attach the map file that was in the car with the issue, anyone able to look at it and see if there is a issue please? Croydon setup.pclr And here are the pinouts of how i wired it.

Hey guys. Have a 2jzgte and a thunder i wired in, but now on the dyno its having some ignition breakouts at very low boost, like 7-10psi. I had a haltech previously and ran easily 30psi+. So i copied all my wiring from previous setup to the new link thunder pinouts and car starts and runs fine, its only once on dyno and under load and boost when it starts giving issues, so now im wondering if i have installed the wiring properly! Does anyone have the pinouts of 2jzgte stock oem wiring where it goes to the ponouts on the link thunder ecu? It would help me see if ive connected it properly and double check my wiring, as im now lost. I will post later when i get home how i did my wiring exactly and maybe someone will see something wrong, but im at work now so hoping someone has the info and i can double check. The dyno operator CRD in sydney who is dynoing it has been talking to link technical and were told the software setting seems fine! Thanks in advance.

Awesome, thank you, i will try that.

Ok. Looked through the software to set it up and came up with one issue. The traction control was easy, select the DI and in the select table i selected "traction control switch disable" and then setup the pull up resistor and on level per this threads recommendation. With the boost control, im a little lost. Select a DI channel, go to the table to select "something to switch off boost solenoid" but i cant see anything like that! There is a "stop switch" but i dont think thats it? What do i pick in the selectable channel so the ecu knows that the switch connected to my DI channel should switch boost solenoid off? Thanks.

P.S. do i just use normal chassis ground or do i use the ecu's sensor ground? Cheers

thank you for the reply, great help. Btw, sorry... i meant my abs sensors are connected to Di channels d11,12,13,14 and those channels on the thunder have a high frequenzy (i forget high high but like 5000/6000hz)?. So im hoping thats enough? Any reason why some things work with toggle and not momentary ad vice versa? So i know for future installations? Thank you again.

Hi. Have a link thunder and supra jza80. 1). Ive connected the 4 speed/abs sensors to the correct aux channels but want to install a simple on/off toggle switch to disable it on the fly and for when needing to do a warm up burnout etc. Can someone tell me how i would go about wiring a switch like that please? And if a on/off toggle switch is ok to use, or do i need a momentary switch?(someone said a momentary must be used so need to double check?). 2). Kind of same deal with wastegate solenoid. Ive got a 3 port , 2 wire mac solenoid, one wire powers the solenoid via ign +12v, the other wire (earth) goes to the aux channel at the ecu. Can i put a simple 2 pole on/off toggle switch in series with the earth wire that goes from solenoid to ecu aux channel??? And again, toggle ok or momentary switch a must? Thank you. Danny
