Yep, I'm pretty sure the Link G4 and the rest just 'interpolate' between the maps depending on E. The only true flex fuel ECU would come in a factory implementation? (eg. Commodore VE flex).
 
Hate to say it but the Nissan/GT-R crowd seem to be way ahead when it comes to E85/flex tuning, so I think it's worth checking out how they have been doing it. 

Ive been speaking to Trent from Chequred Tuning that done the GTR
He can do it to any ECU that has a spare digital Input.
He uses some parts from Zeitronix

Such a common topic nowadays. Suggest talking to your preferred tuner about what they're most comfortable working with. Haltech usually gets my vote nowadays though.
 
Just to touch on knock-control. That's a real hit & miss & would require careful calibration on a built motor.

Adaptronic E420C? E1280s if you want to run flex fuel.
 
Other than flex fuel what are you needing? Both do sequential for 4cycl, inbuilt map etc. Classic Performance are comfortable working with them also.
 

Apologies for resurrecting this old thread, though I felt that it would be best to continue it instead of starting a new one.
I am considering a Link G4+ for my ST205 Celica, which has a GEN3 3SGTE - http://dealers.linkecu.com/TST205Plus
I like this ECU because I don't have to change any wiring. I'm good at wiring, though I couldn't be arsed. I have done enough wiring on the MR2 race car already.
I know that it can use the existing wiring, though I would like to use a wideband O2 sensor with it so that I can do my own on-road tuning, and ideally self tuning in the same way that the Haltech can.
Does anyone here have experience with using this ECU with a very stock GEN3 setup and Wideband O2?
Getting a copy of someone's completed map would be helpful too.

Hey Glenn,
I was looking at same couple yrs back for my 96 gen3. But same, couldn't find a base stock map & didn't want to spend the coin puttjng on dyno.

If your interested, download the tuning software for link ecus. I've got one running my gen 2 3sge with an Innovate Motorsport wideband O2 sensor and simply used a base map that came with the software.

I believe there are a couple of celica base maps there as well and also 3sgte mr2 maps.

I can double check when I get home.
 
EDIT: I've checked the Link Software, it provides a base map for a ST205 Celica (listed as for the Xtreme version of ECU).

OK thanks. I'll check it out.

Hi, I've played with a Megasquirt plug compatible ECU on my SW20 at one time and used some PC software, Tunerstudio, to look at what was going on.  A crazy amount!  Something that was interesting was that Tunerstudio tried to suggest some mapping based on a few accelerating runs and other runs.  I know that this is pretty crude without dyno output power measurement however it seemed that the missing factor was for the PC software to know the output power.   I wondered if anyone has considered real-time torque measurement, maybe a straingauge & wireless module on one of the driveshafts?  Even racing pushbikes can have realtime watts now so it should be possible on a car.  Some of the pushbike measurements are indirect estimates and I noticed someone suggesting a similar indirect measure of a straingauge on an engine mount.  Indirect estimates wouldn't give absolute measurements but even relative measurements might be useful enough for optimising power output.  Any thoughts?

FYI I found another ST205 in Sydney that has a Link. I'm going to use his tune to start with on mine. I'm stoked!
He said the car felt much more responsive with a proper tune when compared with the OEM ECU.
