do i Need an aftermarket Heat exhanger?

At my level do I need an aftermarket heat exchanger?

It's not like your car will explode without one, but it's a VERY good idea to do, along with a head cooling mod.

It has the head cooling mod.

What is the best aftermarket heat exchanger?


Oh and btw someone said that You can read the tempa nd stuff fomr the Odometer is that true, if so how do you do that?


I have the sct x2 with the car, but I dont want to mess anything up with the tune. Cant you make the fans come on sooner?

I would go for the AFCO HE:

You can read some temps and a lot of other stuff on the Odometer display; just hold down the odo reset button while cranking the car, and when it lights up and says "test", let off the button and press it again. Then you can cycle thru the readouts.

You can make the fans come on sooner, but I don't know if you can with the XCal without having your tuner change the tune.

The old H/E question... many will say that you have to have it but just keep one thing in mind. It will not make power on it's own but it will improve your ability to recover from a WOT pull and keep the power you have by reducing IATs.

Hold in your odometer trip reset button with the key in off position.

Turn the key to the on position without cranking it while you are still holding the button.

Continue to hold down on the button until the gauges start to sweep, then let go of the button.

You can then proceed to start the car with odometer in this diagnostic mode.

Use the button to cycle through all the good stuff for your various readings.

Turn off the key to get out of the diagnostic mode for mileage format to return.

wow i do learn something new everyday

Not sure, but I don't think there is a read out in the odometer test mode for IAT2s.
BTW after activating the test mode you will scroll though many different functions/readings, stop at the one you want to monitor and then start the car.
I can't remember if you can still scroll/select after the car is started.
Also of note the ECT reading is in Centigrade.

The Xcal2 however can be set up to data log as a stand alone or as a pass through device for a lap top running SCT's Live Link.

You can scroll. I always just crank the car and hold down the button all at the same time, then while idling I find the one I want to look at. There is no IAT2 on the odo readout.

So with the sct X2 I can run Down the track, and record the run?

So can I jsut check My tune somehow? I dont want to mess anything up, Im new to this sct thing.

i have identical mods to you and i put the afco he on about 3 months and i see a great difference good price and only takes 40 min to put on it runs much smoother

How is that? I mean, how does it run smoother with the afco HE?

:??::shrug:

i have constant pulls with very little heat soak to the blower... its much healthier for the motor a solid purchase for the cobra
