new apexi neo

[frost]

anyone played with one of these yet?
are they as good as they sound? im thinking of getting one.
also did anyone find a solution to the retarding of the timing by the factory ecu problem (even with the earlier safc & safc2)

Work well on 25t Skylines, seen a car go from 160kws to 210kws just by tuning the fuel via the Neo.

Good unit

wtf. are you serious?

dyno sheet please

must have been running Faaaaarken rich to cost 50kw!!!

some cars are tuned quite conservative from factory
50kw is not a unheard of gain.. but it woudl have taken a decent tuner to make that reliable

ha i was thinking of maybe getting 5whp, but if could pull those numbers I'd be really happy. i just put the order in for the neo. i'll post dyno when its installed and tuned.

but on the other topic i remember someone saying you can run with out a oxy sensor and have no side effects. if this true?

if it is then i was thinking don't run it and the factory ECU wont know its running different then factory fuel maps. and in turn not retard the timing as is world do when it senses an off the norm reading. does this sound correct or does the ecu just go into limp mode if the oxy sensor is not plugged in?

No, it doesn't work like that. The SAFC/Neo etc fool the computer into thinking that it's flowing less air than it is by altering the MAP/MAF signal. Less Flow = Less Load = More Timing because the ECU thinks it's in a different part of the map.

Quite often a large amount of these impressive gains are due to the dangerously advanced ignition, not the leaner fuel mix. Unless you have some way of altering the timing then these devices are a sure way to damage your engine.

Ive noticed when shopping around there are alot of ECUs out there so cheap, its just can tuners tune them...

Look at the ones Driven Performance is advertising under a grand was it? or just over for a full replacment ECU, Not bad when a Neos what $300-600 and has no were near the full capabilities..

[chch34]

yea ya may as well spend $1000 and get a LEM or PFC and get that tuned. then ya might see 50kw gains.

na i got the neo really cheap. so thats why i got it.
im not ready for full replacement yet. im still getting use to the car and engine. im not going for full out power or anything, I'll just see what the chassis can do and work my way up to bigger and better mods later on.

fivebob: oh ok i see. thanks for that, i had it totally wrong way round in my mind.
