Will the st205x work with the gen3 3sgte wire harness? I wasn’t able to find any solid answers. I also haven’t slept in 30 hours so that might have something to do with it.

I suspect this will have to be a question for BTI, the error is not very descriptive but it suggest something may be wrong at the dash end.
In the ECU, have have you loaded their LCS template and set up the "transmit user stream" etc?
I have. It’s on stream channel 1 and loaded the LCS file in the stream tab.
i am also getting fault code 17

I followed the instructions for the bti gauge and I get a “No processor “ error at the bottom. I have loaded the file to the ecu can setting and stored it. It is plugged into Can1 on the ECU board. Did I do something stupidly obviously incorrect? I have used the antenna as a 12v source since I do not use the radio. It shows 12v when the key is switched on.

Where are you located? I would also be careful with the o2 sensor set off of the downpipe too far as it can mess with the readings on a wideband (lots of delay). Also you probably don't want to let a wideband sensor sit too close to the turbo like the OEM 3SGTE locaion as it will shorten the life considerably. Remote tuning may also be an option for you. I've been working on characterizing the OEM injectors to make a decent "all stock" modelled fuel 3SGTE base map, but haven't got as far along as I would like yet. I agree it would be nice to have a base map that was correct to run a stock engine pretty decently, and, in my opinion, that is what a base map should be.

Standard rev 2 injectors are 440cc you will need to know things such as deadtimes ect which are harder to get. I ended up buying bigger injectors so got all that data with them. Thats when I changed to modelled fueling as I would have had to retune the whole table anyway. Probably best to ask whoever you're getting to tune the car what they like and go with what they want to use.
You'll run out of injectors pretty quickly if you pushing much more over stock power. I maxed the 540cc's out by 12psi of boost. You're stock map sensor won't go much higher either. If you're having a go at tuning yourself having these limits aren't a bad think untill you get comfortable with how everything works. Stock pistons won't go much higher for long either so there's a big wall to get over at around 300-350bhp. I've found countless things that would have cost me a fortune if I'd sent it away to be tuned and they'd had to sort out.Right now, I am just trying to get it running as close to factory as possible. I am replacing my dash with a BTI since the JDM cluster gave up. I figured I would switch things over the MPH and have a “racecar” like dash.
I really wish you could just set things to a factory tune right off the rip.
Once this is done, I am putting the car in the back burner for a bit. Working on making money off of the stock market thanks to a few friends and would like to eventually go with a k24 turbo. The local shops won’t touch a link ecu. I’d have to drive a few hours to get to a place that will.

Yeah that make's sense. Getting the downpipe off is awfull!! I had to replace my turbo so faught with it for hours. I ended up removing the whole manifold, turbo and downpipe as one unit. That was in a GT4 though, an MR2 will be worse if you've still got the air con compressor that is.
Is the Downpipe from TB Developments? His downpipes are top notch. I'm considering getting one of his turbo kits but I don't really have to funds at the minute.
Traditional fueling meaning you pick a "master Pulse Width" and then all the numbers in your fuel table are % of that
Modelled (VE) means your fuel table is actualy how efficent you're engine is with regards to drawing air in (noting actually to do with fuel). You then input alot of data regarding injectors, fuel pressure etc and the pulswidth that is needed is calculated for the injectors by the ecu.
If you're just starting out "traditional" is easier to get your head round but "modelled" works better if you have all the info it asks for.Yup! This thing is so pretty. It was well worth the money.
So if I had all of the stock info, then I would be alright? I do know my injectors aren’t the 540cc but the 440cc. And that’s about all the info I know.

I believe the wideband will plug into the expansion loom. I have a downpipe and wideband....I just hate the mr2 downpipe removal process....it’s the worst. But this handmade downpipe from England should be worth it.
what do you mean by “traditional”?
-
The dealer I ordered it from included the AIT sensor plug and play adapter and expansion loom with the ecu for a hair under $1k. Sounds like I am good to go minus the tune? Or is the startup tune a factory map or just the bare bones to move it?

Your car should still have a MAP sensor as well as the AFM, you can get rid of the AFM. TVIS is fine as is, our ECU is designed to handle both the Rev 2 and Rev 3 pinouts with no changes to the wiring.
It still has the MAP sensor. I am happy to hear that I dont need to repin anything and can immediately remove the AFM. Next issue is to find a tuner closer than 4.5 hours away...
So that also means I can use a different BoV than my dual chamber as well? And to get it running close to a factory tune, will I need to add a wideband or will the narrowband work?

I think technically a "rev 2 MR2" is the same as the 185 GT4 so it has the AFM for fueling. I think what most people do though is get the latter 205 ecu, use the stock MAP sensor and just add an air temp sensor to do away with the AFM.
Its really odd. It really only changes for that year. Mine has a factory AFM....I would like to get rid of it.
Also installing a BTI dash display since my cluster died.I managed to find this.

Im pretty sure that is what we refer to as a "Rev 2" MR2. So should be correct ecu and the ST205 basemap will work with the minor adjustments in the manual. MAP sensor source setting will need to be changed to AN V4.
If I use AIT, would I still need to change the MAP source? Thank you for the reply as well.
Also, I havent installed a wideband. Would I be able to tune it to a factory tune using the narrowband? -
I am in a weird situation. I have the TST205X for a 93 JDM MR2 with the factory Rev2 3SGTE. The TST205X fits the 17380 factory ECU but Link has posted that its for the Gen3 3SGTE. What do I need to do as far as basemaps? I am guessing that they come with the factory tune already programed? Will it be safe to use with the Rev2 if I remove the AFM? Thank you for the help in advance.
I do apologize for such a newb question.

Sorry about that. It’s a late gen2 mr2
