Fuel injectors get pulsed and the afr remains rather constant... so when the secondary injectors turn on, they turn on progressively and maybe back the primaries off depending on the strategy

its not like bam! they fire wide open and suddenly your burning heaps more fuel....

 

it's the ports opening you gotta watch out for..

 

Yes that's true. I forgot the other one I use to have on a lot was LOOP. At a certain RPM and load the ECU switches to open loop and fuel consumption increases. I mapped this against the RPM indication to set up my best efficiency for cruising.

 

These are the exact readings I want to display once I can start using the OBD port for my Scan Gauge. Right now I am using it for datalogging on my Harrison. Once I get the tune to settle down I will plug in my Scangauge. Thanks for posting the codes!

 

Has anyone had any luck getting a fuel level reading? The FORD CAN numbers didn't work for me.

 

Some good X-gauges including FRT

Ok, I'll give it a shot tomorrow. I want to see what % of fuel is actually left when the gauge is on the E line.

 

Might try this as well, then we can compare. But.....don't hold your breath on this one.

 

I ran through the calibration routine in the manual.
My cal factor is around 13.7% (after this fix to the idle cutoff setting https://www.rx8club.com/showpost.php...&postcount=111)
Now when I refuel the fill amount and the scan gauge agree within a litre and usually within 0.3 litres. I've driven down to less than 5 litres in the tank. (one gallon)

 

I have to go look, I think I'm at about 13% even.

 

Maybe I'm missing something, but aren't the TXDs supposed to be more than two digits? It didn't work for me.

 

For trip data displayed as gauge values, the TXD values are two digits, as it stated in the manual as well. If you follow the procedure as described should work fine. Good luck.

 

Oh that explains it. I haven't been using the trip/mpg features. I was looking for a % full value based on whatever the fuel gauge gets the data from..

 

tonight i will go home and try to get some headway made on some of the other X-gauges.... should know by tomorrow if i'll be able to figure out EGT, Lambda value, etc or not

 

Don't forget the most important - ATF temp!

 

roger! only thing is, i wonder if its even in there? for some reason i thought i saw someone post that there isnt even a tranny temp sensor on this car? i dunno i have no access to AT's ....

 

I believe that comment was made in the context of an MT but don't hold me to that... There might be a sensor on the AT models but good luck tracking down the code..

 

One of the dealer techs confirmed for me that there is a sensor - their scan tool pulls up the ATF temp on this car. I saw him do it on my car, so it is there. Unfortunately, they have no idea what the codes are that their scan tool uses.

I tried the two Ford CAN codes listed in the scangauge pdf for ATF temp with no success.

If you come up with some ideas for the codes, I'll test them out for you!

Thanks!

 

Here is my placement...








Excuse the terrible picture quality of the iPhone.

Does anyone know the accurateness of the XGuage that adds the functionality to show the amount fuel left in the tank? Mine showed 14.7g which sounds perfect considering I had just filled up and done nearly almost 20 miles... anyone?

 

Just started using my scangauge. Had a question about the xgauage. I used the codes for fuel left in tank and the number seems accurate, but when I display it on my gauge screen the three letter name I chose constantly changes to to the word GALLONS and back again. Does this happen to other people? Anyone know if I did something wrong. It is a bit annoying. Thank.

 

Think I would delete that Xguage and start over.
I'll give it a look tomorrow and see what I can find out.

 

it does the same thing for me.. i thought it was standard just so people know the measurement it was using.

 

Yep tried deleting it and it still does it. Although the gauge I set up that tells me how many gallons I've used rather than how many I have left does not do this. That is good enough for me. I can subtract that number from 16 if I have to

 

I cut the little divider between my cigarette lighter and the ash tray and drilled a small hole in the back where the metal ash tray use to be. It fit perfect and keeps the stock look.

 

thats where the rb gauge pod goes though!
