I got the DeMolet Tunable CAI and it's installed. According to Demolet, the 95mm inlet requires that it have a tune or the leaner mix will damage the engine. How much truth is there to this? Others say the same thing but I think most have the 82mm (?) inlet How "immediate" is it? Can I leave it on for the few days it'll take to get a tuner? Does it matter which tuner I use. And just how is this thing "tunable" anyway? So many questions. See I have a 68 Cougar that's my toy, and I don't have any of this stuff...
Thanks in advance
The Tunable Induction CAI will provide more air to your engine than the computer can compensate for and you will be running very lean in terms of air/fuel ratio. If you run it without a proper tune, you should get a CEL (check engine light) warning that there is a problem.
The CAI is "tunable" because it allows you to rotate the MAF sensor within the airstream for best performance. This adjustment should be done when you have the car on a dyno so you can monitor the effect when the position of the sensor is changed from the factory rotation.
I have some outlets that are SCT dealers and include the Xcal2 on their end. With the outlets on this dealer program I simply ship the system separately but anyone calling in a retail order is advised that a custom dyno tune or our pre-uploaded Xcal2 tuner is mandatory.
With purchasing the system without the tuner you could damage the engine.
This is denoted on the last page of the directions.
The SCT tunes are mandatory with the system as they are specific to the system.
Add the tuner/SCT tunes ASAP.
Call the outlet where you purchased the system for the tuner or I can quickly ship you one with the correct SCT tunes.
I called John, and he was quite helpful. Answered all my questions and sent me a tuner for FREE!!. Not really. But I ordered one which is on the way. I haven't yet installed the tune, but the CAI was easy as pie to install, and John has been the best business to work with. I'd recommend the system so far. Once it's on and running, I'll repost.
