2) I asked if anyone else has ran their tune the way I asked to see if there was a benefit in doing so with the higher octane fuel in a 1/4 mile run. COBB told me that with the regular 93 octane fuel and the stock intercooler "could possible cause knocking and that running 100 octane would be a safer bet, but they have not tried it to see if there would be much of a performance gain to be worth it" So, serious question for you: Do you have an answer? No? Then dont troll around with post asking questions that are not advancing the conversation in a positive direction. Its not a big deal if no one has done it. I was merly asking if anyone had. Its not as serious as you think... |

you asked your tuner if they thought it was a good idea, they tell you A) it hasnt been tested and B) it will possibly cause knock / detonation. theres your answer, dont do it. detonation is never a good thing in any way shape or form. perhaps im old school, but i would rather my cars setup be over-prepared for the conditions, rather than underprepared and run it anyway and "see what happens". the smart thing to do is to get the equipment required to properly run the setup you are interested in. if you ran it and had detonation events which according to you "arent as big a deal as you think" and you log detonation events you have no idea what that is doing to your engine or car long or short term. if that doesnt bother you, ok. but i can tell you it sure would bother me. good luck

I asked because COBB TOLD ME to try it out with 100 octane if I wanted to. I’m pretty damn sure that is a green light coming from COBB who designed the tunes and strived for a more conservative approach in the first place. I'm old school too. I ask both users and the tuner about different setups and their experiences. Kind of like what these forums were intended for in the first place. But i digress. Anyone that actually has ran this setup be my guest. Others like this guy don’t even bother... |

You might be able to get away with this on one or two passes in the 1/4 mile or in the winter time, but I would not daily drive this map. If you take the time to reaseach on the forums other people's logs with the stock FMIC you'll see how quickly IAT's rise with the stock intercooler. |

From guys that went from stage 2 to 2+ is it worth upgrading the intercooler in your opinions? I'm figuring 30-40whp difference from the 2+ and intercooler is this about accurate?

My question is why even attempt to run 1+ on a stock car? Our stock intercoolers are already substantially inadequate for stage 1. Any possible gains if you could even achieve them are small and the risks are large.

To answer the question of running a stage 1+ map on a stock car for a 1/4 mile pass it is a bad idea and you won't see hardly any gains. After sitting in line for several minutes(car on or off) your IATs will already be HOT before the run even starts and only get worse when you start trying to push +17psi through the stock IC. The DME will react by dialing back the timing and you'll probably be running negative timing advance by second gear. |

In all honesty the best thing you can do if you don't want to get an ugraded FMIC is to make your own ATR map or have a tuner make one for you. Here is a SUPER mild map i made for a boardmember running e85. Just a couple small changes netted a ~20whp difference. It's on VD so take it with a grain of salt. But it's the Same car, same setup, similar conditions using the same comparo tool.

Does anyone have any hp/torque numbers for Stg 1+? I'm currently running Stg 1 and have the Rogue axleback but I'm thinking of getting a FMIC and probaly a DCI. I just want to make sure I'll "feel" the money I spend on it.....is there a noticeable difference between Stage 1 and 1+ FMIC?

I've got to say that the firmware update and the maps that Cobb just put out make a world of difference. I was running Stg1 for the longest time because the Stg2 map felt more like Stg0... The latest Stg2 map actually feels stronger than Stg1 now, thank you Cobb!

Just a comment here - I've gone from Stage 1, to 1+, and am now running 2+ and there has been a perceivable difference each step of the way. Never ran just 2, as 1+ is supposedly almost as powerful (if not more)...
FMIC is def worth it -

Hey guys, I have some ATR dyno numbers to share. The car base lined at 280rwhp/300rwtq and made 404rwhp/460rwtq using my ATR map. 125whp/160wtq delta is pretty good. There is still some room up top in the map to pick up some HP.

WARNING!!!
-------------------------------------------------------------------------------- I just had my yearly inspection done. With newer cars, the emissions is checked through the OBD2 port and not via the tail pipe/dyno like they use to do. I have a COBB tune and I had just reset it for a different grade of fuel. When ever you reflash/ disconnect the battery it clears some codes in the ecu and apparently the ecu is "not ready" for an emissions test so mine failed. The guy said that they needed to drive the car for a while to get the ecu ready. ( I think this is actually true) So 66 miles later after the kid beat the balls of my car, got some tacos, picked up his girffriend, did some burnouts, and baked the oil to my turbos, they were able to get it to pass emissions. |
