BAC5.2 Posted May 11, 2013 Share Posted May 11, 2013 Here ask this question to your tuner. You: How much atmospheric pressure is sustained on Earth? Tuner: 14.7 Pounds Square Inch. That's where a set my wideband for stioch at sea level to tune your vehicle. You: Now, take your left or right hand and accelerate velocity until contact with face is reached.

cryo Posted May 11, 2013 Author Share Posted May 11, 2013 Bac is 100% correct, stoich and patm are not even close to the same thing. Stoich changes based on fuel being used. Patm changes based on....well.....patm..

dudeondacouch Posted May 11, 2013 Share Posted May 11, 2013 Just a little input 14.7 PSI is the pressure pushing against Earth all the time. Yes if it wasn't for that pressure we would all explode from nothing holding the body together. Which 14.7 is considered a perfect combustion of what ever carbon you might be burning. If it wasn't for us wanting to run dinosaur liquids through engines your oil wouldn't turn black. Your exhaust wouldnt have carbon build up. Just some knowledge. Soo how you you tune for other fuels. Propane, Coal, Diesel, E85 is being used and is understood how to tune. http://i41.tinypic.com/apd2qp.gif Link to comment Share on other sites More sharing options...

Th3Franz Posted May 11, 2013 Share Posted May 11, 2013 Dave, how lean do you typically like to go for AFR under full boost on 93 octane? -Franz The end of a Legacy http://www.youtube.com/th3franz Link to comment Share on other sites More sharing options...
Mega Users seabass07 Posted May 11, 2013 Mega Users Share Posted May 11, 2013 So at what point does the body actually explode? Is everything fine at 0.01pressure, but the body suddenly self destructs at 0? Link to comment Share on other sites More sharing options...
cryo Posted May 11, 2013 Author Share Posted May 11, 2013 Dave, how lean do you typically like to go for AFR under full boost on 93 octane? That's a hard question as there are a lot of variables like is the car used for road race, dragstrip etc. Does the car run a stock tmic or upgraded tmic/fmic etc. What kind of timing is being ran etc. I dont really like to try and make power by leaning it out till I see issues, on the dyno I have seen very little power difference between "safe" and "unsafe" afrs.

fahr_side Posted May 11, 2013 Share Posted May 11, 2013 IME power drops off rapidly below 10.8 AFR, but doesn't increase so dramatically when going leaner. So, I shoot for 10.8 on cars that are run hard for extended periods, have sub-optimal intercooling, run often in high ambient air temps etc. Cars that have easier / better lives I tune to 11.0 or 11.2 if they have headroom in intercooling. Every tuner has his/her own preferences.

LegacyDan Posted May 13, 2013 Share Posted May 13, 2013 LC1 Wideband 02 sensor- One of the most common options for people right now, Bosch sensor, logworks software and cheap guage options as well. Dave Does this one come with all the neccessary cabling to input the AFR into your laptop while logging with romraider for example?

jpierson Posted June 14, 2013 Share Posted June 14, 2013 So probably been covered but my gauge jumps all over the place from 14 ish to 20 on idle but when driving I will let off the gas and it goes red to 20. What's the deal. Oh ya its an innovative. Sorry new to Subaru's and this things all done up Link to comment Share on other sites More sharing options...
cryo Posted June 26, 2013 Author Share Posted June 26, 2013 The car should idle between 13.8 and 15.0 depending on compensations and ethanol content, it is normal to jump to 20 during decal.

McDowell Performance Tunin Posted September 11, 2013 Share Posted September 11, 2013 Dave, I enjoy your write ups. I appreciate the effort you put in to explain the concepts of tuning and how/what they affect our cars. I've been using an Innovate LM-2 for tuning local cars requiring a wideband. I like the handheld readout and logging. Its treated me well as a portable solution for tuning cars' without a wideband already installed. 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...
cryo Posted September 12, 2013 Author Share Posted September 12, 2013 Does this one come with all the neccessary cabling to input the AFR into your laptop while logging with romraider for example? Im looking at this one exactly: http://www.innovatemotorsports.com/products/lc1.php I'm not sure how I missed this, sorry about that. Normally all that's needed is a serial to usb adapter OR a laptop with a serial port already built in *Dell is good for that* Wiring up the LC1 to the car is per the instructions. -Logan- Glad to hear you enjoyed it, I think it helps people to understand in simple terms.

Brett Posted October 4, 2013 Share Posted October 4, 2013 i'm stage 2 tuned with an 11.1 afr (downpipe only) and it put down pretty good numbers. but it's not any faster than the cobb stg1 map from the ap. i'm making 300wtq at 3300rpm and 248whp at 4900rpm. yet at the drag strip, it fails to trap over 100mph. should i have my tuner re-tune it, or take it somewhere else?

cryo Posted October 4, 2013 Author Share Posted October 4, 2013 Well I'm assuming your referring to the stock 02 sensor readings when you say 11.1 which is the lowest it can read so true afr's are actually unknown. What were the differences in trap speeds between your stage 1 cobb tune? regular trap speeds for a stage 2 car are about 98-102mph from what I have seen. I doubt its directly related to your afrs. Did you have it dyno tuned and that's where the numbers came from? what was your base line? There are a lot of variables to consider but a stage 2 custom tune should run quite a bit different than a cobb ots map. Have you spoke with your tuner about your concerns? Hope that helps.

Brett Posted October 4, 2013 Share Posted October 4, 2013 i went from running a 13.5 @101.2 stock, down to 13.8 @99 stage 2. yes, it was dyno tuned and the base numbers were 228hp @5600rpm and 265tq @3600rpm on a dynapack. my tuner is currently at VIR, so when he comes back, i'll have it checked over and possibly revised.
