Hey guys i recently been trying to find out more on my car, i ran some numbers and found out i had a Cobra MAF Sensor, so just tonight i dug out the Computer to see what i have. Found out i have the Cobra Computer the X3Z....I have heard both good and bad things Was wondering what ya thought and should i switch? Im guessing the previous owner got the Ford Racing Kit, that came with the Computer, 70mm MAF sensor and the 24lbs injectors. The only thing i am not sure of is if i have the 70mm MAF sensor (b/c i dunno how to check). But i Have the computer and 24lbs injectors. But the thing is i have other mods, and i have heard that the Cobra Computer doesnt go well with Other mods, especially cams. Now the guy told me it was rebuild, it has TrickFlow Upp/Low intake and Aftermarket heads, 190LPH pump, MSD, and so on. But with a new cam "supposibly" should i switch computers to something else? When im done working on it i want to tune it. So i would like to know the Pros + Cons of the Cobra Computer if any one knows that would be awesome! But let me know what ya think and what i should do, i dont want to be robbing myself of HP or something if i dont have to be Thanks guys! - The Novice.

Yeah i have a rough idle but i figured it was the cam, i dunno. Im thinking maybe it has a chip, do i have to get the Computer out and open it up to find out? btw 93Hatch did you seem to get better performance with a different computer, or was it hard to tell since ya couldnt get it to run right. Finally, if this computer sucks so much why did they make it in the cobra's. Does it have any Gains from other computers? Or is it all Con's and no Pro's to this Darn thing?

ive heard it works fine with the e303 cam, my car ran like shit idled terrible, would die on my when i was coasting to a stop

lets see i went from that computer to a mystery one sean had with no numbers, ran ok but still died and would hunt for an idle sometimes, went to an a9s, car ran a little better, still died sometimes like if i was turning and idling at the same time, then with the a9l my car idled the best and hasnt died yet or tried to find its idle

I keep on thinking that they guy had a S/C on it before he got rid of it, but its just a guess. I dunno, the car seems to run decent, i gets up and goes, but i figured i just had to fix the timing or something, its runs quite rich and have been trying to get that figured out, would that possibly be b/c of the computer? That would be nice to know, it has been annoying me a lot. I dont really know anything about this Cobra computer and whats its good for and bad for. Well thats good to hear that ya got your car fixed! Of course let us know when ya get it dyno'd Also im gunna have to pull this computer out and its jammed way up there, can i disconnect it or will it cause the computer to reset or do something dumb? I have the battery disconnected. Also That heater w/e unit on the passenger side, the large black thing and ducting under the glove box, can i remove that and keep it out? Thanks for any and all help guys! - The Novice.

theres 2 like plastic holder shits on both sides of the computer, pop those off and the whole thing will slide down then just loosen the 10mm bolt in the middle of the harness, the bolt wont come out but youll know when its outa the computer, and the only way the computer would make ur car run rich is if its chipped for a supercharger or something, which youll be able to tell once you remove it

And i know you know what your talking about since ya just told me ya changed your computer out like 3 times For me its really tight in there, and i have little room. I was thinking of taking out that black venting and fan or w/e it is. Can i do that or is that a bad idea, i dunno if its the heater or just ducting. But i would like to get rid of it anyways if i could its just extra weight. Is there any reason why i shouldnt or couldnt or any thing i should watch out for, tips, and so on about it? I would appreciate the help. Thanks a lot 93Hatch for your help on the computer matter. Make sure ya let us know when ya go to the Dyno, i really wanna know what you'll pull.

Was wondering if i can get rid of it no problem, plus it makes it hard to get at this Computer, i can bearly see any screws, infact i only see one if i really look up in there. Heres the pictures of the think i was trying to explain below, if anyone knows if i can ditch it no problem or if its a good idea to do so or not let me know, thanks guys! Attached Thumbnails

I have been looking and trying to find out more about it but have only come accross gerneral stuff, like the less agressive timing curve and something to do with its High speed limiter or something like that, do you know what they are talking about by chance? I couldnt find anything real specific about it. Does it have a governer or cut out the fuel after 80MPH or something? Am i going to lose top end with this thing on? Also i still have to check b/c i dunno if i can take that thing i posted pics of yet, but if i get that off ( can i ?) and find out that this computer is Chipped is it possible that it fixed the timing curve and took out this High speed cut out or w/e this computer supposibly does at high speeds??? Really sorry to keep asking you for help, but thank you a lot for all of it!

Hopefully these things are pritty durable, b/c its up in there and ill have to be jurking and pulling it pritty hard to get it out. Also, (if ya can tell from the pics) There computer is attached to this black clip at the bottom, i can disconnect that and get at the screws correct? Thanks for your help!

fastest i went was like 100 when i had that in my car so im not sure about the governer, and the only way it can see you being able to have the chip reflashed if ther is one is if a tuner near you uses that same chip
