Will Report what I can find

 

So I contacted Epifan as well regarding the radiator fan issue. Just got a reply back:

Going to test when i get home and validate before posting this information in the S2 thread as well.

 

Fan speed vs coolant temp... this is found in the "Test" section under 2D Maps. There is a graph, but nothing relvant to graph.

Here is what the temp voltages equate to based on my ECT sensor scaling map:

S1 ON : ~97C
S1 OFF: ~94C
S2 ON : ~97C
S2 OFF: ~94C
S3 ON: ~102C
S3 OFF: ~98.7
S4 ON: ~109.6C
S4 OFF: ~106.7C

The expression for calculating the trendline of my coolant to voltage graph is :

y = -0.7544x5 + 10.127x4 - 52.966x3 + 135.17x2 - 191.66x + 172.91

where 'x' is the voltage. (yay math)

 

Good news so far. Got the fans to kick @ 190F sitting idle and letting the temps rise. Not sure which of the two params that one is (S1 ON or S2 ON). Fan didn't turn on when i shut the car off so I assume that is either S3 or S4.

 

edited : epifan also just sent me the def file, will check it out.

 

got the map , there is another 2d map called ?Rad Fan Switches, I *think* that might have something to do with the "after car shut off fan turns on" setting? dunno yet, no S2 to test until Friday

Another new settings I requested was the "actual" RPM limiter,epifan found 3, 9000/9500/9000, not sure which one is the actual

interesting thing is there is another new 1d map, ?Rad Fan Mul, 0.14 ? O_O

 

Hrmm I actually dont have those additional maps. Not sure if its a S1 vs S2 thing or the fact that you have Pro?

 

Maybe, its all for S2 maps

This is the one that i have right now

 

Yea totally different than mine. Must be an S1 thing

 

It's for S2, probably bcuz I requested epifan to make all those changes first, he sent me just the map alone and ask me to test it out for him .

the RPM limiter for S2 is wrong in the first place, I was like really? 7K ? for an automatic maybe , still not 7K dude lol

 

Yea I couldn't understand the RPM Limiter map ... on mine it has 4 lines :

7000
5500
9000
6500

I figured it was teh dynamic rev limits and the actual rev limit

 

I wouldn't mind seeing the ignition off fan maps for an S1. Mine has always turned off with the key while others fans will run for a good 5 minutes post ignition key removal.

Any S1s try the def file... Not sure if these'll even show up for an S1 and/or not Pro.

 

That's more like the Warm Up Rev Limiter than Actual Limiter,

Now the new def file has 3 RPM Limter settings, just gotta find out which one.

I didn't pay much attention to the Car Off Fan on thing. if there is a seperate setting for it, I think it will be something high like 105 Celsius on S1, cuz on S2 the logic are key has to be off, Drive by wire off, E-MOP off, and ECT temp HAS to be HIGHER than 110C (230f wtf?) .


on the S2 there is a Radiator Fan switches settings, "That" might have something to do with what the fan does when it matches the ECT volt settings for the fans. I assume there is something like that found in S1 as well. will check it out when I'm done with this S2 bs lol

 

so wait you confirmed that the OMP map isn't correct??

Eeek ... now im getting very worried about the changes I thought I was making and the changes that actually happened.

 

Another thing that is really confusing is all of the "A" and "A?" tables ... There are a bunch.

VE vs VE A
Leading Timing vs Leading Timing A
Trailing Timing vs Trailing Timing A
Oil Injection (Load) vs Oil Injection (Load) A?
Oil Injection (Throttle) vs Oil Injection (Throttle) A

 

Not verified yet, gonna try to get a log this coming friday.

I wonder what VersaTuner is like on the S2.

 

here is the OMP map from VT ... looks very similar to my ME map

 

As it should .... unless someone f**ked up ......

 

yep. just validating with nyc

 

Just had my first ME scare!

Was flashing..then at 99% I suddenly got "Unknown Error". The dash cluster went bananas. And the car went dead silent lol. After I validated that I didn't make a mess in my pants, I shut the ignition all the way off, then back to on and tried to flash again....


...... worked

phew ...

 

So I have read many posts on here to realized that I had 700 more posts to read. I didn't feel like reading them all. Is it decided MazdaEdit works well? Last I knew it was crap and they didn't want to update it and all sorts of issues. On a stock RX-8 what kind of gains are you looking at if any? besides up idle, and omp?

 

I dont recall it ever being "crap" except that it was really an infant product when it was first released. I have been really happy with it. Might not be as pretty as VT but it really gets the job done. As far as any gains, I cant justify with any hp numbers yet, but car is scaled properly, and afrs are sitting pretty at the common 'rich best torque' numbers. With the adjusted ignition timing it is super smooth pulling all the way up into redline and feels like it even wants more.

Fan on, adjusted idle, increased omp all provide a nice added protection to the vehicle as well

 

What did you end up paying for it? I want it for the added protection for now. But plan to turbo my car in future, one day.

 

I believe itwas $219 for the personal version (all you really need if you are just tuning one VIN), plus the cost of the Tactrix 2.0

 

I had that scared at hmm I think the 5th time I used it

I Was flashing a S1 and at the first stage, when it was supposed to "Erasing Flash", it suddenly froze and I almost **** in my pants.

luckly after I restart the car and flashed again it worked. jesus

after that, I bought couple of spare ECU, and I ALWAYS carry them with me when I do flashes, JUST in case something ***** up I can get another ECU and use IDS to flash it back to stock first.
