I would think the modification/s that would require a different performance configuration would be considered a "major" modification i.e. headers, cam, headwork, larger throttle body, individual throttle bodies, (maybe a HFM), etc.
: JC chip modded for HFM? Im confused now... is there another chip specifically if you have just the HFM upgrade?
: : I think you can mix and match the parts b/c my friend has a 95 M3 w/ 540 HFM, Eurosport chip(JC chip modded for HFM), and ECIS Euro CAI. His setup works fine. I think it only matters if you get an HFM.
: : : Gang:
: : : Read over a thread WAY below where JIM C stated that running an upgraded intake with just "normal" software may cause the DME to dump fuel into the cat to cool the mix.
: : : This occurs under fairly extreme situations.
: : : Thus the need to upgrade to software with intakes in mind.
: : : [slight paraphrase so don't kill me]
: : : Questions are:
: : : 1. If one was to just bolt in an intake with no software upgrade, would the same happen?
: : : 2. Do different intake types really make that much of a difference in HP/Torque/Airflow enough to warrant an ECU reprogram for each specific intake. I.e. only dinan software for dinan intakes, only JC software for JC intakes?
: : : I would understand that the respective companies would only use their intake for tuning, that makes sense.
: : : But, does the airflow between the ECIS, Dinan, JIM JC, Homemade K&N really differ that much?
: : : So what I am saying is that dinan, jc, etc. rewrite software to optimize and for safety, an intake bolt-on. But does the variance in intake flow really differ enough to make us also buy the intake and software from a specific vendor.
: : : Why can't we mix and match as long as the software includes an intake "script?"
: : : Thanks!
