archer1.8 Posted October 18, 2012 Share Posted October 18, 2012 Is Stage 2 OTS safe to run permanently? Did some searching as well as asking some friends and they said they had some problems with overboosting. So is stage 2 ots just a temporary tune until you can get to a tuner?

ripemeat Posted October 18, 2012 Share Posted October 18, 2012 it will work temporarily. it's not the smoothest, just ensure you have no boost leaks and you have a COMPLETELY stock intake setup. if you overboost, choose the LWG map and try again, if you have a good amount of learned knock, switch to the 91oct map to be safe. better yet, if you're worried, use the stage 2 91oct map...

archer1.8 Posted October 18, 2012 Author Share Posted October 18, 2012 I am running the stage 1 93 map and its great and reliable. I have an AP1 so I cant really data log or anything, and I dont think it has an LWG map....just a 91 and 93 map. I guess if I were to load the stage 2 91 map and run 93 octane map with a shorty downpipe and sti up pipe I would be ok? Also peak boost is 18psi correct?

ripemeat Posted October 18, 2012 Share Posted October 18, 2012 using 93oct with a 91oct map is very safe. so if you're worried, use the 91 map with 93 gas, less chance of knock. your downpipe and uppipe setup should be just fine with the stg 2 maps. stage 2 boost is 18psi on the ap Link to comment Share on other sites More sharing options...
iNVAR Posted October 18, 2012 Share Posted October 18, 2012 OTS Stage 2 target boost on the AP for an 05 lgt is 16.5 psi Link to comment Share on other sites More sharing options...

stuck686 Posted October 18, 2012 Share Posted October 18, 2012 my new car has been running stage 2 ots tune for 91 with 93fuel for over 1 year now and its running sharp those maps compensate for mix and match parts so i will be getting a tune when my hi flow cat is welded in. power is my least priority i want it to have proper timing, fuel,air Link to comment Share on other sites More sharing options...
archer1.8 Posted October 18, 2012 Author Share Posted October 18, 2012 16.5 psi sounds good to me. 18 seems a bit high for stock pistons Link to comment Share on other sites More sharing options...
ripemeat Posted October 18, 2012 Share Posted October 18, 2012 18 is certainly not high for stock pistons. over 20 then I'd start to worry. Link to comment Share on other sites More sharing options...
Rester5350 Posted October 19, 2012 Share Posted October 19, 2012 16.5 psi sounds good to me. 18 seems a bit high for stock pistons Might not be safe for the top mount, but the guts should be fine as long as you keep an eye on things. Link to comment Share on other sites More sharing options...
archer1.8 Posted October 21, 2012 Author Share Posted October 21, 2012 ok thanks for the help guys...would 16.5 be ok for the top mount Link to comment Share on other sites More sharing options...
cryo Posted October 21, 2012 Share Posted October 21, 2012 If you are concerned about the tmic separating pm barmanbean for an eta on the next set of bulletproof tmic kits. This insures it will not cause you issues at reasonable boost levels.

BAspecB Posted October 26, 2012 Share Posted October 26, 2012 I will chime into this thread as it pertains to the cobb stage 2. I noticed that cobb has a stage 2-SF map on their site that is suppost to recal the maf for their sf intake. My question is that it says 05-06 only. Why is that? I quite positive the intakes/maf are the same all the way through 09. Anyone have any thoughts or knowledge on this? Link to comment Share on other sites More sharing options...

ChefRacer Posted November 8, 2012 Share Posted November 8, 2012 It definitely does use too much fuel all the time. Cobb's maps run rich so they can be used for all different cars. I ran an accessport until I realized how rich my car was running and how much knock the ecu was seeing. Link to comment Share on other sites More sharing options...
ripemeat Posted November 8, 2012 Share Posted November 8, 2012 errr wrongggggg. they run rich in open loop. idle and cruising the ecu will still target 14.7 and cobb attempts to keep the fuel trims as close to zero as possible. it wouldn't be uncommon to see some small single digit negative LTFT values, but thats not a bad thing and not necessarily a rich problem- unless your trims are greater than +/-6%, then its a mechanical problem or you're not using a stock box and filter with cobb ots tunes. its better to have negative trims than positive.
