This was originally posted on the org but I will repost the same message without linking to the thread.
This thread is for people who have or are planning on doing both the LMS intake and the Technosquare ECU reflash. I posted partial information on another thread but decided it needed a more thorough explanation. I have discovered the hard way( this is too long of a story in itself) that some precautions need to be addressed and some information known before deciding on these two mods. I am posting information that was discovered with some experimentation with Tadeshi at Technosquare.
We discovered when experimenting with one new stock '05 ecu and one modified(my original) TS ecu that having both of these mods at the same time without the necessary compensatory parameters in place will lend the '05 VK engine to run slightly on the lean side. I qualify this to the 2005 FX45 becasue that is what I have and do not know if the ecu on the 06 and later are the same, but I suspect that they are. Also, it should be made aware that the 03-04 FX45 ecu used a narrower 02/emmissions band then the 05-present(possibly) which uses a wider band. This can be a pro or con depending on how you look at it. But in my case it was a con.
In regards to the LMS intake for the FX45. If you have a 03-04 then installing the intake with or without the TS ecu reflash will be fine and probably a little better with the TS reflash performance wise. Also, if you have a 05 or later FX45 and have the stock ecu and have no plans on doing the TS reflash then installing the LMS intake will not be a problem.
However, if you have or plan on getting the TS ecu reflash I recommend telling them that you have the LMS intake (or if you have another aftermarket intake) so they can compensate for this. Because the VK tends run a bit lean with the combination of the two. But if you have just one or the other and not both at the same time it should be fine. If you plan on doing both in the future I suggest getting the LMS intake first and then the reflash with the necessary compensation for the intake. Tadeshi can make the necessary corrections but I do not know what the involved cost would be.
