I dont dog on ems upgrades. Only that a fmu/bipes can work great up to a certain extent. I plan on doing an ecu upgrade down the road. But to say it's more reliable isn't really correct. I think saying it's more tuneable and adjustable is more acurate.
I could run this setup for years and years without a glitch, heck corky is building his new kits this way, with only the option to run Xede.
Do I have lots of adjustability? no. Can I get rid of my rich AFR after 5.5k? not easily. Can I run higher PSI? not really. Was that my goal? not yet.
A lot of guys here are looking to piece together systems and make around 160-170hp or so. I'll always recommend and easy setup for them, no reason to complicate things. Yes you can do a lot more, but technically a fmu/bipes setup can work just as well.
I'm not trying to attack you at all, but sometimes I feel like ecus are overkill. Not all the time, not at all. I was in awe when I witnessed Tom's and Bruce's GReddied miatas make over 200hp on 1.8 injectors, with perfectly flat AFRs.
I can currently run 305 injectors at 100psi and get enough headroom for around 275BHP, I don't see to need to upgrade yet. I could for sure squeeze a little more power out of the system, and I could benefit from pulling fuel in the upper rpm ranges. I really think it depends on the users goals, $$$, and how much automotive knowhow they have.
And besides, if I agree with you all the time then it's just no fun. :gay: Seriously, I hope there are no hard feelings.
