4 pin connector and ODB2 reading

Hi guys
I've a 2k13 SWT 600 with a 4 pin connector on the side panel.
I'm from France and here we have a supply of "E85" (85% ethanol 15%gasoline). I want to convert my SWT and for that I need to read in real time the ECU LTFT correction.
My question is: did someone here tried to read from this 4 pin connector the sensors? Do we know if the reading is possible ? (ODB standard protocol)
Thank you

Hi clicmaster. I cannot answer your question but putting E85 into an old motorcycle engine doesn't sound like a great idea.

Why not use E5 or E10?

Hi
In France we do that, no big problem if you respect between +15% +25% motor fuel mix and you introduce E85 smoothly at the beginning. Need a E85 kit as well to increase the motor fuel mix.
I have a 2005 French car 100k miles, did the job and it works great!

The SWing does not use an ODB2 connector. There is a diagnostic connector but all that does is switch the FI indicator light into diagnostic mode that blinks out fault codes.

Thx
There are cable adapter to ODB2, does someone tried it and maybe read something with ODB2 software?

Lots of IF's here. If the PCM is programable then it would work. E85 takes almost twice the fuel flow of gas to run properly. Honda uses PGMFI system on SW old type design from the 1980's up to about 1995 on cars at least in US.

Injectors won't flow that much and or fuel pump may need upgrades. Injectors usually can only flow + -
30% even at full duty cycle.  Ethanol has only 60% the BTU's of pure gas add 15% gas it's still needs more flow. Without a true Dyno and exhaust gas measurement it's risky to run an engine very lean burnt valves, fried pistons.

Another thing to consider is the fuel lines and pump most likely not designed for E85 10% yeah but not the stronger brew. Rubber seals and pressure regulator seems to be a problem on some SW's with it failing and dumping lots of fuel .

As I told you, my car is from 2005 and no problem. We are a lot to use it in France even in motorcycles. As I explained, E85 is a combined fuel 85% ethanol 15% benzine. We use "ethanol kits" connected on injectors pins which increase the injection time so at the end the E85/air mix to be sure you are in the good range.
But as a starting point I prefer to be able to read the ECU monitoring (LTFT) to see how it works now before modification, that's why I need to know if it's feasible or not

This may help from the owner manual page. 212 It is list on this site.

Was unable to copy the pages.

The answer is no PGMFI System doesn't support LTFT readings.

Ethanol kit increasing injector duration if fine but if injector can't flow enough fuel at max. pulse with the fuel type it will have a lean A/F ratio.
E85 has no benefit on this engine nothing to gain in power or HP. Modified engine increased compression ratio, turbo yeah. E85 has about 110 octane and 14-15 to one compression ratio would still make the same power as gas.

E85-E10-E15 around in US. for years but that's the Government pushing it with a bunch of B/S on improved Emissions and such. Ethanol takes just as much energy to produce-refine and ship as gas and delivers less fuel economy. Big scam. I'm still waiting for my SW replacement bike that can ride all day with a 5-minute recharge.

Ok guys thx for the info. I understand no LTFT info can be read thx
I forgot to explain why I want to do that, it is not for power increase, it is just because here the E85 is 50% cheaper
