[quote=Jules]can get power n yet save petrol! WOW! u guarantee this claim one or not? :beer: [/quote]
i have one installed on each my family’s cars in australia… so yes it has worked for me…
ok let me briefly explain what this is..this is a piggy back ecu.. which “Optimizes” fuel EFFICIENCY… please keep that in mind… stock standard ecu always run very conservatively and running on richer than needed settings… therefore this unit can calibrate the AFR to optimal settings which in result uses less fuel… wihle gaining more power can be tuned via the ignition settings in this chip… after installation on the same throttle pressure u gain more power… using a lil less petrol too.. u will also notably feel more throttle response..results can be proven immediately after installation and tuning by the tuner… =) usually to get this u have to ask for a power run on the dyno with the AFR graph shown.. all cars have different results… i was saving roughly around 10% per full tank in australia… but i have not yet tried it in malaysia cause of fuel quality differences and also atmospheric differences… so if u ask for an approx figure.. i cant give u an accurate one… as all my experiences were based on australian fuel and weather =)
however due to price increase i will be installing one in the next few weeks after i have done an overhaul on myengine =)
ahhh..the Unichip…the main cause of electrical problems that dogged Ashraff’s MME team last year, and led to his early retirement and walk back to the Sepang pits…I remember the Unichip…don’t use it on a Lotus for competitive reasons…..other cars Ok I guess…
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….

It’s the matter of the tuning method from the tuner skills not tuning software/hardware.
There are so many things need to consider when tuning. Fuel mapping, throttle position, ignition timing, MAF sensor, fuel mixture etc. There a time when to run lean and rich fuel mixture in normal driving, qualifying and race. Running advance full IAM all the time wont guarantee you success in race.
Tuning also depending on altitude level, atmospheric pressure, weather, road, circuit conditions etc.
Most of JDM cars runs RON 100 fuel mapping. Tuner can fine tune the map by retarding the map value to compensate with our crappy 97 fuel for more response and reliability on the engine. Smaller value mapping figures means more headache and complicated for the tuner to fine tune the machine like the motec m800 tuning software.
Most modern cars on the road nowadays runs on self learning ECU. It means let say your car starts to knock, the ECU would detect the error code to protect the engine.
So the best method to do tuning is by on wheel tuning instead of dyno machine tuning for better performance.

wah!…you’re not just an apprentice AJK Makan….we should see u on the podium then! 😎never had that issue b4 .. however emanage was known to blow distributors 😉 later on only were there firmware upgrades available to prevent that from occurring!
also recently on the jgtc races.. my friend tuned the corvette that races on the Asian super car club driven by a guy named micheal.. also in australia there is a gtp race where my frined tuned a couple of gt3sand ferrari 360s XD and it does make a big difference on those cars 😉 i sitll have the pics on my fone.. u can check it out just remind me on saturday and ill show u =) i also have videos of the corvette on the dyno but on my laptop 😛

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]you sound quite familiar with this stuff however its hard to say which type of tuning is better… its about feasilbility and a mix and match of both to get a good tune… a quick explanation, tunning on dyno is very expensive… so therefore it isnt feasible to tune everything on the unichip on the dyno…so usually ppl go on dyno for performance tunning on as many rpm points as u can in 1 hr… or 2 hrs or however long u can afford with load… however if u want a “fine” tune…road tuning can enable tuning on throttle dabs, part throttles etc etc this is to improve the throttle response…. road tuning can also be used for tuning on the low throttle configuration to emulate normal road driving styles to be more fuel efficient 😉 can u imagine trying to tune ur car for performance on road in full throttle on forth gear… meaning requiring to constantly rev from 2-3krpm all da way up to max rev… alot of times u just run out of room in kl traffic kekeke it is still possible todo full throttle tune on road but just a lil more hassle thats all there is no better tune… its different typesof tunning for different types of application

[/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
what ur basically talking about is torque multiplication which is different matter.. u will see that da lower gear the higher the hp… what u want is something as close to 1:1 as possible… u r trying to tune the engine with little gbox ratio assistance..at higher gear it is more likely to lean out, coz holding rev longer.. another less important thing is when u do powerruns on low gear the graph will be too short and too less detailed inbetween rpm for 3k – 4k rpm… in a gear close to 1:1.. u actually see a wider graph which helps abit in tuning as u can see things in more detail… so basically all ignition and fuel maps look at what rpm u are on regardless of what gear ur in..for eg if u tune in 2nd gear then u drive top speed in 4th or 5th, the revs increase slower, which require more fuel unlike 2 gear, at certain revs, the engine req X amt of fuel and timing, in 2nd gear it goes thru that rev fast and is not crucial to the A/F , but on track u hold that rpm point for longer periods of time, if u tuned on 2nd gear, no doubt it will lean out…i hope this answers ur question

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.
