Mods : 2.6 pulley, K&N highflow filter, shorty header, 42# injectors (not recommanded with a pulley that small), stock DP, custom Magnaflow 2.5 catback, one step Colder Brisk Racing Plugs, 94 octane, 3500 feet elevation (boosting 15 PSI).

Anyone know why the scanner didn't log KR, IAT2 and commanded AFR ? My Interceptor gauge can log easily KR and IAT2 ...

 

Holy hell!! Please take off that pulley. Your probably super lean. Go to the HP tuners forums and ask how to get KR and iat2 ect.


But about the tune I feel bad for your motor you should really go back to a 3 in pully please!!

 

My AFR ends at around 12:1 logged on a dyno. But I know it's running at the limit. That's why I'll put the 60# injectors in a couple of days. I will maybe downgrade to a 2,9 pulley too.

 

i have a log of a 2.8 with 42lb injectors showing an injector duty cycle of 118%
do not go above 4k rpm with that 2.6 on....thats a blown motor waitin to happen
stay safe till your 60lbs arrive bro.

 

you're pushing it. but not as bad as some cars that i have seen. if you want, i can send you a config file for all that fun stuff. so the kr and other some other things show up.

2.6 isn't great, drop to a 2.8, and you will be much safer

 

Now KR, IAT2 and commanded AFR shows up, thanks to Fast06SS advices. As far as the injectors are concerned, I already received those 60# injectors, but was a bit affraid to install them cause of the fuel economy. HPTuners doesn't allow to enter a flow higher than 63.5 lb per min, but in fact these injectors flow a lot more than that at idle and when running in vaccum (no load).

Thinking about it, 50# injectors would be perfect for a 2.9" pulley setup, and they flows 63.5# @ 80 KPA vaccum, exactly the maximum allowed as per HPTuners software.

 

Good thing you have those things showing up. All really important. My fuel economy with the 60# is almost as good as stock, well, when I don't get on it.

It doesn't look like your having much knock at WOT, looking at your timing, but it does look like you might have some at the shift. You'll need the injectors cause your going static around 5750rpm. Post some more up once you get the 60's installed

 

fuel econemy is still never going to change as much as what you do with your right foot

i bet with a little bit of playing around in hpt....and a light right foot...you can equal or surpass your MPG with 42s

 

his injectors are not going static.

 

Dude are you logging bank 1 and bank 2 trims? The only time I have seen trim logs like that are when someone was logging both banks and the bank 2s were showing up 100% all the time, so the histogram was averaging bank 1 and bank 2 LTFTs. This is easy to fix. Open your scanner and go to your table view. Highlight LTFT bank 2 and delete from your table. Then do the same thing for STFT bank 2. We don't have a bank 2, so those numbers will only screw you up.

 

They turns static at 6741 RPM.

17.8 Ms x 6741 RPM divided by 1200 = 100%.

Yeah I was logging Banks 1 and 2.

 

Thought so. If you are using those trim logs for anything, delete the bank 2s.

 

I should have said that I'm located at 3500+ altitude and I'm boosting "only" 15 PSI with that 2.6" pulley.

 

Noticed yesterday while cruising at low speed that IAT1 rise (slowly) and keeps rising from like 80 to 120. The sensor is on top of supercharger and probably gets heated quiclky.

Then IAT2 do the same up to 160, without flooring the car !

Shitty cam/head/M62/2.6 pulley combination LOL.

 

watch your a/f. if they start to skyrocket, then they are going static. i had this problem before with the 2.8 and 42's. i now have them under control and they don't stick anymore.

in short, it all lies in the hands of the person with the laptop.

 

Dude did you put the sensors/PID in your "table"? If there were some way of sending you my table and config file I would. I'll send you some snapshots and you can go from there............
BTW I know I'm rich.....took a long time to get a good afr With my last setup......taking alot longer to work this one


BTW the thing was to your log file.....not you

 

Yeah that's was the problem. I had them entered only in the charts, but not in the tables. Now it's working.
