TRUE! Motec is overkill and very expensive.

sorry WhiteAp1 but what I meant to say was that you cannot chip/over-ride the factory ecu with like hondata, chrome or neptune. With hondata you need to replace the whole unit.
In regards to cars not running properly, i don't know much about tuners in melb, but in bris, car's that run Motec/Autronic, most run like they came from factory. When you buy the unit, the base map for your car is pre-loaded into the ecu to it'll drive normal immediately. My mate's evo runs the m800 and it starts and drives the same as when he bought it only faster due to tuning and bigger turbo.
In regards to your comparison of the stock s2k running only 250klms per-tank, i'd recommend he go get an A/F gauge as it seems his motor is running rich.
Back on topic, I'd recommend James @Revzone in Melb to tune as I had him come to bris to tune my turbo dc5. It's runs great on stock internals and does over 400klms per tank (including spirited driving here/there).
call up andy from akmotorworks. He,ll be able to help u out.
honda-Tech or another Honda specialst behind honda tech cant remember the name of the top of my head.. or check up chasers..
I know what you mean. Only ecu's from 06 and up can be flashed
I agree, but I dont exactly mean the car wont run properly im saying depending on the ecu you may loose things like the imobiliser, guages and even sensors or have to replace them, not to mention poor fuel consumption. Considering the small gains and the high price, IMO I dont think this is worth it.
Sorry I musn't have expressed myself clearly. The s2000 with the M800 only gets 250 per tank with 150 atw. I have a very cheap and simple piggy back ecu getting 153 atw and get 450 per tank on average. Again my point is an expensive and highly functional ecu may not be the best option. If the OP is after power, go FI or be humble with the limits of NA tunning. Which ever your choice be wise with you spending. Expensive doesnt automatically mean big gains.
digging up an old thread~
anyways does anyone here run the basic mods (intake/headers/catback) on stock ecu?(no piggybacks!)
if so, would u mind telling me how much km/tank of fuel ur getting?
i used to run just the injen intake and that got me about 440km/tank.
changed that for j's intake and a catback, and getting 390km/tank.
thinking about going aftermarket headers and by the looks of things, i will be getting less than 390km!
if i wanted to get a tune on a/fr to improve my milage with the basic mods, would a vafcII do the job?
any suggestions of other piggybacks? or should i just leave it as it is with stock ecu?
I ran a J's intake with TP and Exhaust and got pretty much the same fuel about 420ish - 440 a tank with average driving and afew WOT's.
To answer your question in short! Yes a vafc, piggyback could/will improve your mileage, but at what cost? and is it worth it? That depends who tunes it. A deadshit will more than likely lean it out too much, and you'll see an increase in power with decent mileage, but this will more than likely result in some type of mech failure such as a burnt valve. Tuning it properly is very important. With someone that understands Honda's, there fuel maps and there high revving nature, only a very slight improvement is possible. IMHO it's probably best not to toy with ecu settings while your still with basic bolt on mods. It is possible to trim some fuel out to get better consumption as i mentioned as the factory fuel map/a/f ratio are quite rich. By why change it? Honda did this for a specific reason. As a rich fuel map is generally regarded as a safe tune. So many are eager to attempt or find something Honda didn't, regarding ECU/Fuel maps, unfortunately in this circumstance little or no fessible gains are to be had. If there was gains to be had, you'd find plenty of info on what to do.
Using e-manage ultimate I got 11kw over stock with I/H/HFC/E and i got 40km more out of my tank. but this tuner leaned it out and was great on WOT but not so good daily, so got it re-tuned for more daily friendly driving which was much better and the car felt much smoother.
with the mods you have i'd recommend emanage ultimate or blue.
i should of added that this is my daily.
i drive at least 350-400km, so a fresh tank of petrol every week.
so im not looking for more peak power gains, more reliability on fuel consumption although any gains is a bonus =D
