fuel race tuner

[harleyguy]

Hi Mike
Could you give a little insite into these particularly pn# 32136-05. I have stock 05 Deuce fi and want to do se heads, 251 cams, 10.5:1 1550. Will this look after increased fuel needed? Are they hard to use? I am new to efi. Also, should I be changing ignition?
Thanks Again!

The new versions allow for both increases and decreases in fuel. For owners who wish to do their own tuning "by feel", they are not a bad way to go so long as the performance upgrades are minor. Your upgrades are a little more than minor and would be outside the capabilities of the "Fuelers". Even though fuel needs are addressed the MANY other background tables and constants are NOT addressed (motor size, cranking fuel, warmup fuel, idle steps, etc.) and are affected by the changes your proposing. SERT also addresses the ignition. Downside is SERT is much more expensive, requires a proficient tuner and dyno time to really get the best use.
