Backfiring normal?
I was just wondering if some backfiring from the exhaust is normal. My car does it. Usually when high boost, or when I put the car in neutral after driving, it will for a sec. I hear this on srt4's, sti's, other turbo'd cars all the time. It sounds normal for a FI motor?? Am I right, or wrong? If not, would you think its running rich. The smoke that comes out when shifting is a greyish, so that should be fine. as long as it isnt white or black??

Rep Power: 0 I was wondering. I havent driven my car much in the last month. And the weathers changed about 50 degrees. I need another tune, but was wondering why every srt4 and other factory boosted cars are backfiring as well. Doesnt make sense.
Isnt backfiring cause by extra fuel being burned in the exhaust, or in the IM (which is terrible for our car seeing as how its plastic)

Michalo knows, hell have to get tuned just as much as me, hehe.
My car doesnt backfire nearly as much as most cars I hear. Only half the time, and not too bad most the time, its very quiet, doesnt mean it isnt bad though.

Rep Power: 0 I have another question. How do cars that are factory turbo'd not need tuning every season?? Does it adjust by temp, or do they just run it rich? My friend and I were wondering this.

Rep Power: 307 my guess is that their ecu's are programmed to input data and output response based on that data. Much like the stock ECU on our cars. Our ECU's don't do that, because our only means of tuning (besides aem ems) is to piggy back...and these piggy-back devices cannot compensate for these changes in climate and atmosphere.

Sophisticated algorithms used in conjunction with MAF, KV, BARO, MAP and/or knock sensors with also TPS, O2, AIT, OT readings to accomodate for a *almost* normal running condition despite weather, altitude, octane etc.
Ahhhh the joys of a stock turbo'd car.

YES TUNNIN will show if its good or bad....... Backfiring.. could mean as many bad things as it could be good...
Mine did but that was cuz i was runnin like 11's and sometimes 10.9's on my O2 Charts./.. when it backfired,, I trough out Black smoke from the exahust > GAS/RICH
I luved it though.. haha
It made it look like if it was as strong as a SUPRA>. they do it all the time..
Its was only when I was in boost... When i drove normal. it never did it!..

Rep Power: 256 on certain cars it can happen with simple mods, take for example the wrx/sti, all you need is an atmospheric bov and a tbe and vioala you have after fire...
your just not burning all the fuel and running rich for an instant and it hits your hot exhaust tip and kablamo!! tune

Rep Power: 256 So why not just get like an AEM EFI were you can pre tune your car for seasons, save the data package on you computer, and then ever season instead of tuning it, just swap the pakage out? in the end wouldnt that save money?
