I've been having issues with my Rebel kit recently and was considering sending my PCM to OTT to flash their tune to fix my problems.

My problems are that I'm running uber rich and in second and third gear the car starts to pull back because of the knock sensor pulling back the timing.

Will the OTT tune have the same kind of issues, but not as bad? because I've heard from someone who ran the OTT kit that its not as noticable but still there.

Thanks in advance for your input

 

think here.....

is it overly rich, or to much timing?

the car wont pull timing due to fuel, just KR. thats normally caused by to aggressive of a spark map.


none the less, ya, I'd bet the OTTP flash will do you some good.

 

When your car is running to rich the engine starts to knock, to compensate for that knock the PCM retards the timing. I've had issues like this with my Cav because it was running a bit rich. This fuel managment problem I'm having now is the worst I've seen it. The tune was complete garbage.

 

I have 0 problems otther than he 60lbs misfiring once in a blue moon... but thats the nature of them... Their tune is good... if you want to tweak its a good base...and its just fine not messing with it at all

 

in order to reach a "rich knock" stage of combustion, the flame front must almost be stalled out thus causing the pressure wave split.

this would mean your bordering on the low10-high9 AFR range.

i've seen some **** can'd tunes in my day, but i hope the rebel tune isnt that bad....

 

I would look for something else besides ottp stage1

 

I have codes poping up, engine knock, un-even idle, black smoke pouring out of the exhaust, among other things. That seems like a great tune eh...... Plus the quarter mile times I have gotten are worse then with my stage 2. You can't tell me that this tune is fine and dosn't need any kind if tweaking.

I don't know the advanced side of things, but I'm just going on my experience with this sort of stuff. I'msorry I can't be more precise. All I know is that the car runs like a bag of ****, I listed some of the problems in the above post

 

I get ya man, i'm just hoping the rebel guys arnt that bad.

 

your tune is fucked... i was talking about mine from ottp

 

in a nutshell

in a nut shell

 

I hoped the same thing, I heard some good things and decided to give them a chance. But you can ignore the facts, the car runs like a bag of hammers. I'm sorry if I came off as abrasive, but I'm just frusterated.

 

send it to ott they'll fix it for you

 

Ya I'm sure they can, but will I have the same kind of fueling issues but just less severe?

 

no.. what kind of injectors are in there?

 

60#

The rebel kit is the exact same as the OTT one minus the PCM flash.

 

yeah **** rebel... send it to ott it WILL be fixed

just make sure you list all your mods... they tune to it

 

I assume you have the OTT kit, do you have CEL's? do you feel the car pulling back its timing when racing up the quarter? Hows your idle? is it bouncy?

 

yesm no, no, idle is stable with plus or minus 50rpm for supercharger surge... the ott tune rocks bro... just make sure you tell them you want the COT OFF, and if you go to the track tell them to turn the IC pump to turn on anytime your ignition is switched on

also do you have everything install correctly?

 

COT? and yes, I triple checked all the parts to ensure they are properly installed.

 

Cat Overheating protection.. it messes with your AFR...

 

Okay thanks;

Does anyone else want to offer their input?

 

Drive up to Port Perry and Devon at Powell Raceshop can flash an OTTP tune or whatever you need...call first....

 

ott tunes are different depending on mods....

 

exactly. start with a base tune and go from there. The only Rebel thing I have seen is a 2.4 supercharged conversion that is pure junque, we worked on fixing it, and corrected some of the basic issues, and now Shaun has got it running half decent with a friend's help. What a nightmare. Anything from Rebel seems awful to tell the truth. Listen to 06 Black he knows his s**t....

 

rebel blows, i wouldnt be caught dead with any of their products on my car
