McDowell Performance Tunin Posted June 30, 2010 Share Posted June 30, 2010 I am going to be tuning an 03 WRX on Thursday and needed to flash his stock map to my computer, to start building a map. I also like to take a learning view before to show and expalin how their car is running. This person installed the following the day before and has been driving around: New catless up pipe Full turbo back catless exhaust CAI Here is his learning view. Keep in mind, the older 16bit Subaru's are suppose to have an IAM of 16... Let this be a lesson to those who want to mod their car without some sort of tune. www.facebook.com/mcdowelltuning [sIGPIC][/sIGPIC] Click Here for Stage1, Stage2 and Stage3 Tuning and eTuning Info Link to comment Share on other sites More sharing options...
Boostin1657615274 Posted July 1, 2010 Share Posted July 1, 2010 either removing all the cats or changing the intake can cause problems by themselves without a tune On the search for a new DD... Link to comment Share on other sites More sharing options...
McDowell Performance Tunin Posted July 1, 2010 Author Share Posted July 1, 2010 yeah, I was shocked when he told me what he had installed and had been driving around. I basically told him to stay out of boost as much as possible. But looking at his learning view, he's been in the higher load ranges. Hopefully he makes it to the tune tomorrow... www.facebook.com/mcdowelltuning [sIGPIC][/sIGPIC] Click Here for Stage1, Stage2 and Stage3 Tuning and eTuning Info Link to comment Share on other sites More sharing options...
SpeedNeeder Posted July 2, 2010 Share Posted July 2, 2010 Looks like he is knocking all the way through the rpms under load Am I looking at that right? Good to see there is no knock after 12,800 rpm, hehe. My other car is a 1993 Chevy S-10 Tahoe!

bnguyenbb6 Posted July 2, 2010 Share Posted July 2, 2010 No, that is why you don't beat on it when you need to be properly tuned. Link to comment Share on other sites More sharing options...
McDowell Performance Tunin Posted July 2, 2010 Author Share Posted July 2, 2010 When your ECU is below 16, for the 16 bit Subarus, it basically tries to "fix itself". It may hold boost back some, but you can see it also shows positive numbers, so it's adding and taking away timing, trying to fix the issues. He was running his stock map with a catless exhaust system. (I thought he also put a CAI system in, but at least that was stock, but dirty.) Point is, If you are going to install parts, either have a tuner come to you when you are finished, tune it yourself, have it done at a shop, or an AcessPort. It's best to have the fore thought of figuring these details out before adding aftermarket parts. A lot of people are use to throwing exhaust on their Honda and not having these types of issues. Turbo charged cars are subject to problems thowing on parts blindly. Some learn the hard way. www.facebook.com/mcdowelltuning [sIGPIC][/sIGPIC] Click Here for Stage1, Stage2 and Stage3 Tuning and eTuning Info Link to comment Share on other sites More sharing options...
HpJunkie Posted July 2, 2010 Share Posted July 2, 2010 I installed a catless up, catted shorty down and a perrin big maf and Kn drop-in about a yr ago, have been driving and logging and never saw problems. I guess its cause I didnt make big changes. My friends always argued with me becasue i had no tune and did it. In hind sight I knew nothing of this site or the potential problems I could have caused. I wouldnt do it again but Im glad I had no problems/or any to my knowledge. I recently put on a DP, intake and EBCS but the car is literally 3 ft from me waiting for my map to get here.

Infamous1 Posted July 2, 2010 Share Posted July 2, 2010 I've seen WAY worst, even on "tuned" cars. Link to comment Share on other sites More sharing options...
McDowell Performance Tunin Posted July 3, 2010 Author Share Posted July 3, 2010 Yeah, but he was two quarts low on Oil and has 115000 miles on an 03 wrx with the stock turbo. Runs nice now, However. www.facebook.com/mcdowelltuning [sIGPIC][/sIGPIC] Click Here for Stage1, Stage2 and Stage3 Tuning and eTuning Info Link to comment Share on other sites More sharing options...
keithk831 Posted July 8, 2010 Share Posted July 8, 2010 Interesting how the knock correction seems to be right along with WOT runs. He definitely has been beating on it. Link to comment Share on other sites More sharing options...
keithk831 Posted July 8, 2010 Share Posted July 8, 2010 I've seen WAY worst, even on "tuned" cars. Yeah...like when I took my first LV screenshot of my Cobb Stg2 map. Talk about knock! Link to comment Share on other sites More sharing options...
Infamous1 Posted July 9, 2010 Share Posted July 9, 2010 Yeah...like when I took my first LV screenshot of my Cobb Stg2 map. Talk about knock! That honestly was one of the worst I've seen on a pretty basic setup running a "conservative tune". Glad things are working out with the most recent venture.

Glad things are working out with the most recent venture. You would think that Cobb, having a shop in SLC for dyno testing, would have their maps calibrated for 4500ft elevation. Therefore Utah cars would have the best results. Quite the opposite in my case! My friend has a 2005 LGT 5EAT, and I keep trying to get him to bring his car over so I can take some LV screenshots and log a couple runs to see how he's doing (he's running a Cobb Stg2 tune). He just got his CNT catted DP and he's going to find a catback, then he's going to do a custom tune as well. Link to comment Share on other sites More sharing options...
