Yes, 5% ethanol in my 91, and 80% ethanol in the e85

I have a mix calculator so I don't get too much or too little e85.

1st e30 log using same maf cal and commanded afr as the e15 log. Only diff is load adjusting, Timing, and e30. Looks about the same wot afr as previous. Apparently at least this way of doing it works and is consistent. :) Not bad power so far...

Here is my copy of my ATR, e17 map, and corresponding data log for anyone wanting to open it and take a look. Just unzip, and open the program file, no need to install. It runs independent. DO NOT update ATR or it will not open file. I am on the pre ban version of ATR. :) Download my ATR and...

The maf curve gets way off in the spots I keep adjusting.

Probably about 6, at which point the curve gets too far off. And, no afr change happens at wot. Car has 95k and oem 02 sensors. No other concerns at all. Getting good fuel mileage for a Speed, fuel trims perfect.

Maf v and Maf g's are logged on my latest log.

That is correct. Like I have been saying... A wot maf cal has NO effect on my wot afr. And all maps hit about .7 afr leaner than commanded. The only way I can get wot afr on target is commanded afr. I have been fighting this for quite some time. I would not have made some silly thread saying...

It looks like I am calling my e15 map finished. This is my daily driver tune. I have an e40 map for max power. For whatever reason here are my final commanded wot afr vs actual afr. 3500 11.2 to get 11.7 4000 11.1 to get 11.7 4500 11 to get 11.7 5000 11 to get 11.6 5500 11 to get 11.6 6000 11.1...

Inspected all pre turbo hoses yesterday. But, I better take a good look at the bypass hose to make sure no splits. What is a better way to do a maf cal? I am on an ots maf cal now minus my closed loop maf cal pasted in.

Back to my original question... Does anyone know why I have to command 11 to get 11.7 wot afr? I am talking about my self tune here, nothing to do with Dizzy tuning map. Even ots maps commanding 11.6 see 12.3. Is it something with my car, or maybe because early 07 ecu? My 09 Speed would hit...

No problem Jason. This thread was in no way intended to go against you. After reading my if you want it done do it yourself comment, it sounded like I was being a jerk, but I am just super picky and wanted a go at tuning it myself. During my tuning, I found that no matter what I commanded, I got...

In his email, he said he was targeting 11.1

Not trying to bash anyone, but 12 afr is not safe with stock internals from 3100 to 4600 rpm making 305/367. I want a somewhat safe tune. No, I have not contacted him, I just decided to self tune and am trying to figure out why I have to command 11 afr to get 11.7? Not upset with anyone, just...

Yep, decided to just do it myself. AFR should have been addressed early in tune, not while making power.

Just for my own sanity, I loaded a stage 2 ots map, and only changed injector scalar and specific gravity to match my e85 content. It was commanding 11.6 afr. Drove 50 miles, first wot showed 12.3 afr from 3 to 4k so I lifted. Drove another 20 miles, wot again, same thing 12.3 from 3 to almost...

I read somewhere they released 5000 speeds a year in the US. So about 15000 Gen Won's, and 20000 Gen Pu's. Not sure of accuracy... Not including the Speed6 Found this on automotive.com Mazdaspeed3 Origins For years, Mazdaspeed was recognized as the race-oriented division of Mazda due to its...

using excel and msblackmica's method from his wot maf tutorial video. =/11.8 that gives me correction number to insert into corresponding maf volts in atr

I do when doing a wot maf cal.

This is my commanded vs actual afr: 3.5k 11.2 to get 11.6 4k 11.1 to get 11.7 4.5k 11 to get 11.8 5k 11 to get 11.7 5.5k 11 to get 11.8 6k 11.1 to get 11.7 6.5k 11.1 to get 11.6 After next log I am going to attempt a wot maf cal to get afr even closer but this is best it has looked yet! Did 5...
