Hi, All,
I've been researching the TFI - looks like a great product. I have a couple questions here:
The TFI website has some suggested settings for various engine configs - it lists settings with and without a stage2 download, and the pot settings are lower for the bike with the download. This is where I'm confused.I thought the whole point of an aftermarket fueler is to eliminate the need for a dealer download? It seems that with a stage 2 download, the fueler doesn't need to modify the fuel delivery as much?
I was similarly confused when looking at the canned maps at the Dynojet website - they have maps for the power commander for stock ecu, stage 1, stage 2. Why would you buy an aftermarket EFI controller AND pay for a dealer download? this isn't making sense to me.
I'm changing my pipes from v&h big radius to the straight shot hi lo's. I'm hoping the swap won't need a different map, but worried that it might. I'm considering buying a TFI to be sure it'll run nicely. Right now I have the pipes, Ness big sucker, PC3 with a canned map for my setup. How do I know if I have a stock or stage 1 ecu?? will that info show up on my computer when I hook it up to the PC3? I know I could just trial and error my way to a nice fuel curve with the TFI, but I'd like to get a handle on what's happening before I dive in.
Also, my plan in the next couple of years is to build my engine to 95" or 98", get a nice street port on the heads, and put in Andrews 37 grind conversion cams. Will the regular TFI (vs. the high output/high HP model) work okay for this build? The site says it'll work for 95", various head ports, and "mild cams." Would the 37 be considered "mild" in this application?
Thanks very much for any help.
Jon.
