Remote tuned by member on this site
Magnaflow O/R X
275/50/15 Nitto 555s

Im not sure if the tune is done, Iv tried to contact the guy doing the remote tune like 3 times by email and I get no response. My car is currently on the 3rd revision (Base +3). Also its probably worth mentioning that I drove to the car show which was about 30 miles and had it dyno'd in the first 10 minutes of being there. This is in central texas. It was my understanding that the base tune was good for 585 RWHP per kenne bell website. The curve looks good but 528 lol? Im on the fence about getting it locally tuned via dyno. $500 for a 93 and e85, does this sound right? My goal building the car was to safely make 600 on 93 and 630-650 on e85. From what I've read this is about right. And for the record everyone seemed to be making low on that dyno. The other picture is an M3 with a vortec which he said should be between 550-650. He made 460 : \

Im going to take a few screenshots of the last datalog I sent to the guy doing the tune.

I don't know what im looking for in the tune so I got 3 screenshots from the last logging session. Those look a bit small to read, if you go to my photobucket you can click on the actual picture and use the zoom feature. Dunno how to keep it from getting cropped to crap http://smg.photobucket.com/user/Andrew123654/library/

A dyno is a tool, the actual number can vary significantly. If "everyone seemed to be making low on that dyno" that day then you could be making more power than you think.

IMO, if you want more power your next mod should be a bigger TB.

cant make sense out of those graphs with everything checked...break it down into several graphs with rpm+X&Y with X&Y being whatever you want people to look at (spark,commanded fuel, measured a/f, Maf frequency)

 

[Doug1227]

What sized pulley? Pounds of boost? On 93? It looks like I'm seeing 19.5 degrees of timing advance at 6000 rpm, which is pretty aggressive for 93. I'd definitely have it tuned by a reputable tuner vs the KB tune and then verify everything with logs or dyno time.

It's hard to tell anything in the screen shots you posted, but at 4500 is your AFR .86 and .88 and at 6000 is it .87 and .89?

 

[Voltwings]

You can just post the actual log instead of a ton of screen shots, that way we can open them up on our own. Thanks.

My god. If you are really running 0.86-0.87 with FI, it's matter of days before you blow it up. Post the log file.

You should aim for more power... my 4.6 cobra with a 2.2kb made 600... a 2.8 should get you more!

Who is it tuned by? I kinda went through the same thing here. Almost all local dynos here read extremely low except for CTP. Ill be getting CTP to do my tuning when I switch to E85. I think ive seen this car before?
Whats the MAF flow rate in lbs?

 

[Andrew123654]

I tried loading the actual log but this site wouldn't accept it. If you click on my link to photo bucket you can see the full size screen shots of the logs posted. Is afr bad at .86 to .89? From other threads I've read that is spot on. And timing is between 18 to 19.5

Bv600 your inbox is full.

 

[BV600]

its clear now. 18-19 is a lot if that on e85? should be over 600 with that much timing depending on boost. Fuel pump maxed and not revving it very high.

 

[stroked mach]

no way I would drop that much cash on a blower set up and not have it dyno tune

 

[BV600]

Email tuning is probably just as accurate if not more. Your getting actual street/track load conditions data logging.

On these cars with the front o2's also being widebands data logging on the street is the way to go now. Yes in the past a dyno tune was the way to go but times and cars have changed.

 

[Andrew123654]

Those logs are on 93.

 

[BV600]

That is a TON of timing for 93! For reference on 93 I run 15.5 and on Torco/93 mix I run 17. A Twin Turbo 5.0 I know runs 17 on E85. I wouldn't deal with the tuner and go elsewhere honestly something doesn't sound right. I would data log with knock sensors and maf flow rate.
Can you PM me who the tuner is?
Are you in 41st FA Bde?

 

[Andrew123654]

See if that worked.

.86-.89 lambda isn't that great for even a NA car. I like to see around .84 for a NA car and around .80 for a FI car. I took a look at the datalog and you don't need to be running that car WOT.
