[quote=Jules][quote=FAibS]powerruns is done on the ONE gear which is nearest to the ratio of 1:1 so for eg. if u have a 6 speed da power run will be done on 5th gear
[quote=Jules]wah sounds very good…
sorry, newbie on cars here but when u do power run – was it for all gears like you are driving on road or how? care to share?
more power less fuel – wah Ashraff team sure fix for MME2008 one less fuel stops and can zoom past the porsche….

[/quote]Thanks…..but then we dun drive our cars in ONE gear rite? so how? does such tuning reflect real driving condition? ( disclaimer : I drive my kart in one gear, DD2 2 gears and shifter 6…)
wah mr lamsey – u my sifu man…tabik! LOL[/quote]
As we all understand each gear ratio varies to engine load. To get the balance among all ratios, tuners always choose the closer 1:1 from GB to engine. That is 3rd gear for most japanese.
There are after-market ECU capable of multiplie profiles that it able tune every single gear ratio, this very benefit epecially to auto tranny or Semi automatic tranny vehicles.

neat, balance and practicali assume ur talking about complete standalone ecu.. would love to have one of this myself XD this is a piggy back which still needs the utilise the standard ecu.. the price range in comparison to this is in a different class by itself… and also not usually used by slightly modified or stock cars… this only cost 800 for unit + 500 for labour and tuning.. all up just RM1300 at most, brand new unichips costs RM2200-2400… how much for standalones? XD this is just a cheap basic alternative to fine tune ur stock vehicle or slightly modified vehicle to run more efficiently that is all..
gear ratio..
dc5 6mt = 1st 3.266/2nd 2.130/3rd 1.517/4th 1.212/5th 0.972/6th 0.780 therefore we choose 5th gear to do those runs.s14 5mt = 1st 3.321/2nd 1.902/3rd 1.308/4th 1.00/5th gear 0.838.. therefore we use 4th gear.
civic ek 5mt = 1st 3.230/2nd 2.105/3rd 1.456/4th 1.107/ 5th
0.875 here we again use 4th.gen2 5mt = 1st 3.583/2nd 1.947/3rd 1.343/4th 0.976/5th 0.804 again we use 4th gear
as u can see all cars varies just depends on which gear is closest to 1:1 for the one chosen to do power runs. as u can see its usually safe to assume that on 5mt gb its usually 4th and for 6mt its usually 5th.. but sometimes it could be something else too… always check which gear it is runned at and know ur car’s gear ratio b4 dynoing, cause usually lower the gear the higher the hp, which can mislead u to believe ur car has that much hp when it really doesnt.
anways unichips still available if interested XD turns out this classified thread has turned in to a technical one XD keke anyways reason for sale is that im upgrading to version q+ and sold of some of cars so i have extra units.
i couldnt put it better myself!! =) wellsaid!
[quote=luen]The fundamental facts:
1. Richer in lambda ratio (rich)less power produced. Good thing is, the excess fuel helps cooling combustion chamber. On the other hand, leaner setting better fuel burn efficiency but expense life span of engine due to excessive overheating.2. torque and horse power are relatively 2 different kind of power. That is the different between a lorry able to pull 1 ton trunk but unable to achieve 160km/h. A formula 1 car able to clock 320km/h not able to pull a trunk.
Car manufacturer originally tuned the engine targeted to last longer. The safer choice that original tuning just to rich out a little. Many factors are to consider especially costs. Example, lean tuning depending on rigidity of engine block, pistons, con rods and bearings are the basic facts, this also means incurred the costs of building the engine.
My point is, knowing what power region that is desired and start tuning from. It will be more practical to have better torque than horse power for day-today use. Lean at mid and slightly rich at high end HP for protection.
[/quote]luen it fits most cars 😛
new version of unichip q+ or q is universal fitmy version is a, b, c and d15 which fits most cars!
oh thanks for the correction. I always thought unichip for specific car only…. “UniqueChip” ma haha…
[quote=luen]Unichip… good stuff hehe unfortunately I do not have a BMW kekekeke, Jules grab it 😉 [/quote]
Ya lar it’s universal….
anyhow I am not the only with a BMW and mine is a Banyak Makan Wang version……lol ( its not true just to be truthful )
Anyhow – I cannot handle the power as it is already…..
Free Bump for ur unichip Faibs. ( potential buyer! we have in house consultant mah for this who will help u with the install )
hahahah ur a funny man XD
[quote=luen]oh thanks for the correction. I always thought unichip for specific car only…. “UniqueChip” ma haha… [/quote]power will increase but dont think it will increase 50hp or so hahah u dont own a turbo u have a na.. 😉 for na cars.. AFR is more important so is ignition timing.. alot of bmws running it and have very positive feedback.. just check out bmwclubmalaysia 😉 and it also helps with throttle response 😉 also if u modified ur car it will make ur components and engine work hand in hand and gains will be better! very very cheap already.. was selling for RM900 for my-kart members only RM750… other ppl RM800.. brand new will set u back RM2400 ;)so it is a cheap buy XD and very very limited stock =)
