i just finished my upgrade path
this is the place to ask questions, and feel to ask. people around here are really friendly and helpful. so far, i have not been flamed for asking simple or fundamental type questions. i do not consider myself an expert.
the issue with what kind of chip or other pcm upgrade you want really depends on what you want to do with the truck. most folks only need 1 or 2 programs. you don;t REALLY need 6 programs, but its nice if you have them. how often you need to switch is another thing to consider.
i just finished my upgrade path on my 2000 f250. i wanted 80hp econo for HW travel and maybe 40 or 60 for around town. my goal was fuel economy and i trust my chip vendors advice. so i waited for the warranty to run out and then started doing the other 'pre-requisite' mods. intake, filters, etc.. gauges especially. i did shim the FPR but not the 10K mod.
i was torn between the programmer and the chip too. pros and cons both ways.
costs: dp-tuner.com who is jody tipton has a decent breakdown of costs. the programs are pretty much the same price. chips are about half the cost of the tuner.
with both the programmer and the chip, the programming is done by the tuner (jody tipton, tony wildman, etc...). its pretty much the same program just different methods of interfacing them to the PCM.
while many people like the programmer, based on my other experiences, i do not like making firmware upgrades. this opinion is based on things like routers, csu/dsu and telco type switches, which are meant to get upgraded. when the upgrade hoses the firmware, you always end up putting in the spare piece of equipment and take the hosed one out of service to fix what you broke trying to make it better. i don;t know about you but i don;t have or really want to invest in a spare PCM. SOO, i ended up going with the flip-chip because i only wanted a couple of programs. a chip can be upgraded simply by pulling it out and fedexing to the tuner. a few days time and maybe $20 on shipping is fine for me to tweak it or change it if i have to.
pulling the PCM is SUPER easy and i say this after being intimidated taking it out for the first time. putting it back in, i was a bit tennative, but now in retrospect, its easy and nothing to be afraid of. (i encountered resistance in putting the connector back on the pcm and did not think there should be any resistance so i did not want to force it back together, but the small resistance is ok)
as far as overwriting the program: if you have the programmer then you simply re-upload the 'stock' program to the pcm. of you don;t you pull it and send it back to the tuner to get reflashed. if you have a chip, then you pull the chip. either way, you are looking at 15-20 minutes of doing something if you care about warranty.
you cant really go wrong either way. one just cost more than the other.
on the bright side, you can pretty much recover you money selling a GOOD chip used or a GOOD programmer with programs used.
as far as OBD goes, i prefer the laptop based ones. i prefer to have seperate devcies for seperate takes.
