Does anyone have a MAF calibration table for a Series 2 or the function to convert in Mazdaedit? All I have is MAF voltage. (A calibrated one, not the one in the PCM already)

Would MazdaEdit work on a 13b rew swap or would it be better to run the adaptronic system or get an rx7 ecu?

I would use MazdaEdt to turn off engine codes and then run an Adaptronic. That is the simplest / most "plug and play" option to the swap.

I know this defeats the purpose for some, but are there any people here that will street tune/e-tune an S2? I want an S2, but I want a tuning solution for it, and I have no interest in tuning my own cars anymore.

Any thoughts on rx-8 with lpg?

badinfluence

Depends on compression ratio. Your power curve will be different, and slower to the power band, but you can tune for this.

This is a estimation, but I would think you would want a better seal (Gas pressure) (virgin or quality rebuild engine) with lpg/natural gas/hydrogen. Again another guesstimate, but I think direct injection or direct valves into the chamber would be necessary to make it with your while (to make it comparable to a petrol.) Big benefits for a turbocharged setup! (but you will need to carefully match your turbo to lpg)

I firmly believe it would be worth digging into, but here is the catch or questions to ask.

Will MazdaEdit allow you to tune for lpg/gaseous injections (pWM....etc)?
Do you have an OpenPort2 OBD2 tuner already?
Can you add custom params to MazdaEdit?
Will Epipan support you at all? (vendor of MazdaEdit)?
Are you decent enough with electronics to where you can use something like an Ardunio or CanBusTriple to middleware or create an additional "PCM" to help the primary one with the difference?

not all have to be yes btw, just good things to review. Estimate about 1000 for tuning, software, and 2 hours of time with a tuner over Skype for help/polishing....

My final advice is, if you have a spare car or transportation to your job etc, go for it! Start with making a dual fuel system
Make it work with both at the same time
Taper off gasoline gradually as you tune
Tune over a period of months and keep a laptop with MazdaEdit and your OpenPort2 in your car just in case you have an LPG or Fuel Injection problem and have to switch to only one fuel.

Hopefully you can spark some interest on here and some pros with jump in to help you box. Take some pictures of you doing it, and either help or hate will come. Hopefully help.....

Anyway Cliff Notes to Look up: Instructables Dual Fuel ECU ; CanBusTriple / Middleware ; MazdaEdit ; OpenPort 2; Dual Fuel ; Rotary Compression etc ; Mazda's Hydrogen Rotary

I'm putting this here since I'm guessing I don't have enough posts to make a new thread.

I know with the series 1 cars an AP basically negates the need for the fan relay mod. Before I spend money for this on the s2, can mazdaedit or versatune change when the fans come on? I'd rather just put my $100 towards a tune if so.

Steve Dallas

I believe both MazdaEdit and Versatuner allow you to change fan turn-on temps. I'm sure someone with actual experience will be along shortly to confirm. I have not messed with that aspect of my car yet, as it is still under warranty.

eyeguy

Thanks Steve. Yesterday afternoon I spoke with a local rotary road race mechanic yesterday who confirmed your statement. He uses mazdaedit.

i can confirm that VersaTuner does allow you to change the fan turn on temperature. i have done it to mine. left the primary at 186 and change the secondary from 223 down to 205 to help regulate temps during track days.

RIC SHAW

I have been using Mazda Edit for years and with the series 2 RX8 have found if the temp is changed for high speed fan it wont respond as set. the fan still comes on at the OEM setting even when the temp is dropped below this. but then the fans will come on and run at high speed after engine is turned off till it cools alot.
has anyone found this ?

This has been brought up before . I think someone figured it out but can't remember who and when that info was posted .

jasonlel

I'm facing the same issue as well as RIC SHAW, anyone have a solution?

Witi

Okey saddly i got a problem....
Right now i want to tune my 8 and i know i need to start with my MAF map but i can't find a table in mazdaedit where it shows the g/s or the V of my MAF sensor
because of this i allready tuned a lot of other things including the AF ratio
Now i dont know if my maps are correct or not because i got an aftermarket intake (AEM) and im sure that the MAF is reading wrong (because i think the ECU is not listening to me completly) i dont know what to do
Got any ideas?

The table you are looking for is called ..... MAF

Witi

Sorry i didnt mean the table in mazdaedit it self
my Problem when i connect mazdaedit to the ecu i cant read the life data of my maf sensor
the table does not Show up in my dasboard and i cant switch to it

It is definitely there ..... did you click the 'RX8 can' window ?

Witi

Yep: "Mazda RX8 (A) CAN ECU"
Does the (B) change anything?
i will try it tomorrow maybe there is something that i missed

When you get to the first window ...select the..................... .xml file NOT the ............................. rx8.xml file . That should fix it .

Witi

this was the problem
thanks a lot for helping me out
