tolerate Posted May 19, 2014 Share Posted May 19, 2014 Hi all, I'm working on my tune and would appreciate some pointers. Could you guys take a look and tell me whats going on? My acceleration is fine, but after I start to cruise, it leans out and starts struggling. Tolerate_tune.zip Quote Link to comment Share on other sites More sharing options...
mattb3562 Posted May 20, 2014 Share Posted May 20, 2014 If you're still experiencing that heat soak problem, I wouldn't think it would be a good idea to throw more fuel at it. Quote Link to comment Share on other sites More sharing options...
tolerate Posted May 20, 2014 Author Share Posted May 20, 2014 i idled the car for about 30 minutes. and the fuel rail was pretty cool. I dont think its heat soak anymore. Quote Link to comment Share on other sites More sharing options...
Xnke Posted May 20, 2014 Share Posted May 20, 2014 Where is the intake air temp sensor? Quote Link to comment Share on other sites More sharing options...
tolerate Posted May 24, 2014 Author Share Posted May 24, 2014 (edited) after the intercooler Moreover I discovered a couple of new problems. After the car warms up ~10 minutes in the spark advance goes haywire in tunerstudio, without any user influence. (e.g. playing with VE numbers) and today again after taking the car battery out, charging it, and plugging everything up, i was working on the hot start values when it struck again. When i say haywire I mean, the spark table values all change, and the spark settings also change. Also after returning the battery to the car, the AFR is reading 7.35 and 22.35. I checked the project settings for wideband, same problem, etc. I tried calibrating it, maybe I did it wrong. Will try again tomorrow. This memorial day weekend is going to suck. Help me make it better. Edited May 24, 2014 by tolerate Quote Link to comment Share on other sites More sharing options...
Tony D Posted May 24, 2014 Share Posted May 24, 2014 Why on earth are you pulling a battery out to charge it?!?!? You have a charging problem, and need to fix it. AC voltage from a bad alternator can do all sorts of things like corrupt your code, etc (so can your laptop comm chip, or electrical noise.)

tolerate Posted May 24, 2014 Author Share Posted May 24, 2014 (edited) the alternator is charging. after 20 or so cranks of hot start, it kills the battery. I dont see the problem but if its a bad as you make it sound, I'll only you use the jumpstart and leave the battery in. I treid recalibrating and noticed hte LC-1 LED is never on, found a place on the ground that was stripped and repaired it, still no working LED, I'm about to take a 9volt battery to make sure the LED isnt dead. Also made sure I had 12 V switched. Edited May 24, 2014 by tolerate Quote Link to comment Share on other sites More sharing options...
tolerate Posted May 24, 2014 Author Share Posted May 24, 2014 re calibrated, tested the LED (dead), and have a haywire AFR, oscillating all over the place (e.g 7-24 and back in <1s). My google-Fu is telling me that I've got a bad sensor, i'm going out to get a replacement. Quote Link to comment Share on other sites More sharing options...
