Brettus, have you experienced any quirky flashes? Been working with Kane to get my S2 tuned. Scaled the MAF at idle, once we got that down we started scaling through the RPM band. Here's the strange issue ... with my latest flash (slight increase in scale) I can't seem to build up any LTFT (except at idle). Stuck at 0, even after multiple drive cycles totalling over 2 hours of actual driving.
Reflash for good measure?

Don't think it is something to be concerned about - so long as you get the end result you want.

Hmm, my LTFT has been at 0 for a while, but I thought it was simply that I had the MAF well tuned for closed loop. I'm going to stick with that theory for now...
Paimon, it might be worth comparing maps to see what has changed. I would start by reverting anything other than the MAF table to stock.

I wait who is going to tune like a panspeed their rx-8 on rx8club ? wait to see p-port or side ported renesis engines and results

OK, I have my closed loop AFR well tuned via calibrating the MAF table. However, open loop AFR does not match the values set in the "Open Loop Fuel" tables.
Is the best approach to simply tune the values in this table to provide the desired measured AFR, or should I go back to tuning the MAF (or some other?) tables to try and make the Open Loop Fuel table values match the actual AFR?
Thanks for any help.

You might also want to consider the possibility that the open loop maps don't correspond to the gears they are supposed to . I've yet to see a car where they do . Now that I think about it ..... all this maf scaling and Ve map adjusting BS could have arisen because people have not realised that simple fact (with the ol fuel maps) that I tried to tell the forum about 4 freaking years ago .

Scaling the maf in all but idle and cruise is .....................overrated to say the least.

on what? Im getting tuned with help from Kane. On a business trip now but when I get back we are going to continue working.
I will be honest, *knock on wood* I have had no problems with mazdaedit. Never had the program crash or crap out during a flash. Just always do a "get information from ECU" before a flash to make sure the communication is kosher and you should be good to go.

It does lock up occasionally ... especially if i am monitoring then turn the ignition off and leave it a couple of minutes . It almost always locks up the program and I have to do a 'cntrl alt delete' reset to get the laptop going again.

Me either - and i've done over 100 flashes on my 8 and probably another 50 on other peoples.

Just asking cause I have my eye on an S2 for sale here, White 09 with under 15k miles . . . so as soon as my townhouse rental sells, I am pulling the trigger and getting it (as long as nobody else gets it first!!) So I am glad to see some hope for an FI solution for the 8. I probably won't be doing any upgrades until least next summer so I am hoping someone becomes the test monkey for a solid upgrade.

The 1-2 and 3-4 maps do in my 2005
not sure about 5-6 since I typically never get there, maybe next year when I run some track eventsAs far as I've ever seen, altering either of those two maps worked for the gears being tested (2nd vs 3rd @ WOT) without impacting the other
I'll specifically test for it once the car is back together early next year
The issue is IMO if you don't have gear specific maps the fueling is all over the map (lolz) due to how quickly the engine is accelerating relative to intake valve operation during WOT

But I agree that tuning by gears is def. preferable for the reason you mentioned.
Have yet to see anyone test this specifically on a USDM RX8 with the AP so would be very interested in your findings .
