FMU vs HONDATA
 

what are the advantages and disadvantages of the two managements??

thanks

Please tell me you're joking? ::)

Hondata is an ECU based tuning software that is used to control a lot of different aspects of your ECUs operation. Most popular, obviously, is the ability to tune fuel and ignition maps for N/A and force inducted applications. Downside, ECU needs to be supported, and it the cost can be $250+ depending on the application needed.

An FMU, fuel management unit, is a fuel pressure regulator that increases the amount of fuel pushed through the injector at each pulse as the amount of manifold pressure increases. The injector pulse duration does not change, and the timing doesn't change. Advantage to an FMU, they're cheap, and can support low boost setups easily.

FMU = cheap and shitty

Hondata = not cheap and not shitty

Hey, what about SAFC vs. Hondata? I know Hondata is the best, but SAFC can't be too far off as long as you are max boosting around 10psi.

Re:FMU vs HONDATA
 

S/V-AFC or any AFC for that matter still has the limitation of scaling your MAP sensor signal, thus, advancing your ignition timing. This can be a limitation for those who require low end power (SOHCs) that would be lost from retarding your base ignition timing to compensate for the advanced timing of the air fuel controller.

im planning on running a minime with a v-afc/450's.

???im going to lose low end power because i'll have to adjust my base timing?

Re:FMU vs HONDATA
 

::sigh:: Yes if you retard your base timing.

Run good gas, and put your base at the stock 16 degrees advance, run good gas, and you should be OK. Obviously, check for detenation, but normally, you should be OK up to 8psi (I have tested, personally).
