Can i data log AFR and Boost on my X4?

  • Yes. The tuner can accept analog inputs such as AFR and Boost signals for data logging.

will this overwrite old tunes? recently bought car and dont know if it holds old tunes

Omen00gt

  • Many Cobras tend to have a chip in the PCM. You would want to remove that before using a new flash tuner or the tuner won't be able to connect to your PCM. The tuner will treat any tune on the car as the stock tune when you go to load a new custom tune to your vehicle.

Question Resolved

I just ordered the BAMA X4/SF4. I currently have JLT CAI, SLP Loudmouth Catback exhaust, and I'm installing 2.70 blower pulley. What heat range spark plugs would you recommend. NGK Iridium IX seem to be the way to go, just want to see what heat range 7 or 8 and what kind of overall gains in HP would I be seeing with all mods noted above?

svtoz

  • It would be hard to say how much overall gains would be produced, as there are many variables which ultimately drive the results (ei. fuel type, humidity, timing, boost level, elevation which includes atmospheric pressure, et cetera). Regarding the NGK plugs, I would recommend at least one step colder plug, or even two steps colder, depending on the power the vehicle produces. I would highly recommend speaking with a tuner in your area regarding your specific application.

Question Resolved

do i have to have a bigger mass air meter with this product? I got the jlt as a gift and it says to use a bigger mass air but from what you detail state i do not. So is it alright just to bolt on w/o the bigger mass air? Also you said no tune required. Correct? The tune would only be neccessary if i would go with a bigger mass air. Correct? Lastly would you reccommend a bigger mass air?

Mlvicino

  • M, if you want to maximize efficiency & performance, get a tuner. This will program the onboard computer for the increased air intake. U don't need a new MAM but a larger one increases air/fuel mix even better with the tuner. You could just install the CAI & see what happens!

    I found the filter element hits the fender liner. I tried seeral ways to get it to fit but had to force the line back into position. I would think being a 2nd Gen it would fit better.

    The jlt cai was a little harder to install into the flinder than it seemed, but we'll worth the trouble. So much throttle response and hp added. The X4 is the best part of the combo, getting the custom tunes are great and easy to get.

    Good Flow and Awesome Sound

    Of course a CAI is better than a stock intake on the Cobra, especially if you run a smaller pulley, but the biggest benefit I got from this CAI is a much louder blower whine. Love it!

    Nice Hp & Torque Gain

    I got this due to a lean indication when my 03 Cobra was put on the Dyno at Lamotta Performance in Longwood FL. We brought the tuner and the car to him and it made a huge difference. Before: 412 RWHP . 425 RWTQ. After: 465 RWHP 465 RWTQ.

    Review from JLT Performance Next Generation Cold Air Intake (03-04 Cobra)

    Amazing power!

    Me and my dad were convinced that there is no way you could gain 26-30 wrhp from a simple intake but wow what a difference! picked up 1-2lbs of boost and much better throttle response! Eaton is considerably louder. My 03 cobra breaks 2nd gear wide open now! Very happy with the power but it could have fit a little better! but overall great product and it was put in the car in less than 1 hr.

    well worth the money! took about and hour to remove/install. only issue i ran into was the filter hitting the splash guard. but other than that its amazing! I even gained 2 psi of boost. i used to push only the stock 8psi but now the gauge is showing right at 10. The eaton is definitely louder and i can feel some power gains as well

    Good product easy to use. Just wish it came with the window mount as advertised by sct when advertising the product was being publicized at car shows and magazines. The ford magazines and you tube has plenty of tutorials on the product if you have any questions it came repackaged by bama tuning and I must say just the tuning for life made this a deal. Dyno tuning usually goes for around 400 and I plan on doing that later but the can tune works fine. The best feature is the data logging. The dyno tuners recommend this tuner also for its capatability to work with the sct maf.
