Ninetails Posted June 6, 2022 Report Share Posted June 6, 2022 Hi Link community! I have been searching and reading on these forums some time and I am impressed with the help provided. Briefly I would like to be open about my knowledge in this area(tuning) to be very newbie-ish. I usually take my time to read up on subjects or things I dont understand, but there will be alot of new things for me here. Hopefully I wont be to annoying. Car: Toyota Celica ST185 Carlos Sainz, 2gen 3SGTE. Its my first time setting up a Link g4+ pnp, or any aftermarket ecu for that matter. I ordered it very early on before I intended to use it. Unluckily for me I got the wrong unit. The seller sold me the mr2rev1, and I learned after I shouldve gotten the st205 version for the CS. Problem because it was so long after I had bought it, so I got creative and got the schematics for both and I have replugged\wired everything to work with the unit I got. Its running, tuned a little only on road, but it has died/stalled on me a couple of times which im still not 100% why. My fuel relay was getting very very hot, and I have rewired the whole system so it goes on its own relay now with power directly from the battery, im hoping that was the problem. I was hoping someone could take a look on "todays" situation and perhaps guide me somewhat on things that might look off or weird. Any help is much appreciated. More about the car: 2Gen 3SGTE Engine, CP Pistons 86.5, Manley rods, Acl bearings, ARP bolts, TVIS delete plate, EGR removed, hks super sqv iv, 9 hole manifold, mishimoto catch can, mishimoto radiator, turbotechnics S148 hybrid turbo, apexi straight power intake (afm removed), hks metal head gasket, 3" downpipe, hks silent exhaust, link 3bar map sensor, link can lambda, racerx fuel line, walbro 450fuel pump, mac 3 port solenoid, long iat sensor in intake (coldstartinjectorposition), deatschwerks dwr1000 fpr 4bar pressure (4bar was more stable then 3bar), bosch ev14 1100cc injectors and probably more i cant remember right away. After the car is a little more stable I will get it on a dyno, I just dont have the money to do it right away. Each hour costs quite a bit. Plus I really like to learn as much as I can. I have done everything on this car myself. I have attached the latest ecu file and logg. And again thank you so much for your time even reading this. Cheers.

INSW20 Posted June 6, 2022 Report Share Posted June 6, 2022 Your setup sounds very similar to mine, although I'm a billet ct20b on a 2.1L stroker 3SGTE. That said, I've attached my tune, feel free to compare, but I would advise against copy/pasting the ignition map or anything like that.

Im sorry I was a bit vague in my opening, because I know its a tall ask - but after my car has stalled on me so many times I have gotten a bit "scared" to drive it. And also very uncertain if I have done something wrong etc. I was hoping someone could do sort of a skim through to see if there is something bonkers or red flags. Things that maybe should be turned off\on. Hoping to get control of the knock setup as soon as possible for example. Again thank you so much for your time.

koracing Posted June 22, 2022 Report Share Posted June 22, 2022 Usually if it's stalling when coming to a stop or idle drops too low when putting in neutral you need to do a couple things: 1. when fully warm, adjust idle air bypass or air bleed to the point that the IAC duty fully warm is 10-20%. If no idle air bleed adjustment is available, increase base throttle position and reset TPS calibration when done. 2. Set your base IAC position to slightly higher than whatever duty it idles at warm so that it will work down from a higher idle to proper idle position when returning to idle. 3. After those things adjust hold% up until it returns nicely from a throttle blip and doesn't hang or dip below idle speed target.

Ninetails Posted June 22, 2022 Author Report Share Posted June 22, 2022 Apologizes though, I know it was vast. I have joined hpacademy and will try and educate myself a bit more before I continue. Cheers Kris. Thanks again for all your time. Quote Link to comment Share on other sites More sharing options...
SrSt185 Posted January 15, 2023 Report Share Posted January 15, 2023 Hi, rpms are the same in cluster vs log ? I have 6000rpm in the log but the cluster are 5700rpm+- rpms at idling are similar… st185cs ON tst205 g4+ lastest firmware its possible adjust this?

Adamw Posted January 15, 2023 Report Share Posted January 15, 2023 Most analog tachos are very inaccurate. Some have significant lag also, so they are less accurate under heavy acceleration than they are at lower acceleration. There is a multiplier in the tacho settings that you can use to adjust its span but I would say your 300Rpm error at redline is probably already better than most.

koracing Posted January 18, 2023 Report Share Posted January 18, 2023 There is no tach output on the ST185/ST205 ecu and harnesses. It is driven from the igniter directly to the gauge cluster. Yes, the factory tachs can be very inaccurate, so the one in the ecu log is correct. Quote Link to comment Share on other sites More sharing options...
