i checked with them, their only using dyno tested parameters (test car) changes for your engines. not doing ecu fuel remapping on dyno. from my experience, same engine doesn't mean they react the same way.

 

what they do is plug out your ecu, remapped it, and put it back, do some testing done in 1 and half hour 890 dollar fly...... no dyno result, just telling you OH! you got 15bhp and 16 nm gain from your engine. "we tested already, and got those result (on the test car"Not your car")"

 

btw the reason why i want to do this is that, i have change my exhaust system, air intake system. factory tune ecu runs rich for some reason. By doing this i assume they will adjusting my ignition timing to fully utilities my ron98 fuel i pump all the time to get better fuel consumption.(i am well aware of the pros and cons and risk involve of doing this)

 

Overall, isit worth it to do a remap from their pre-programmed ecu map using dyno test parameters from their test car of your model. all they do it plug out, install, plug back in, do some diagnostic and BANG 890 dollar in 1 & half hr

 

what car are u driving may i ask?

 

my answer to u is yes...

better fuel consumption, better pickup, more power...

all in all better drivability

This came at the right ime....I am also interested in the tunning. But I have same reservation with you.

 

Which is a better call? Re-tunning or Piggy Back.

 

Re-tunning as above I also have the same question in the approach as listed above.

wow wjhr... i din know thats how it works!

 

thanks for enlightening me...

dont like the fact that they dont prove the performance increase to u...

 

my friend tuned his golf gt sport... stage one... was an ECU reflash with Juzz4cars...

damn his car after that really significantly got difference...

It's more of adjust the factory settings. no extra devices.

 

i wont want a piggy back cause of this reason. (maybe wrong correct me if im wrong)

 

The alternative to a proper remap is a plug-in tuning box(aka unichip, etc...). When comparing the two, a full remap is irrefutably the better option. A tuning box sends false sensor values throughout the complete rev-range. This tells the ECU that there is not enough fuel entering the engine. The ECU then over-fuels in order to gain performance. Although performance gains are made, they are at the cost of high emissions, higher engine temperatures, and general abuse of the engine. This may result in poor running, black smoke emitting from the exhaust, clogged injectors, rough idle, and engine cut-out.

 

Bad tuning of a plug-in tuning will mass up your factory ecu. Stock factory ecu will adapt(relearn) overtime you have to do re-tuning again and again which cause a lot if were to find experience people to tune for you.

I would actually prelfer a piggyback or standalone ECU. This is because I prefer to leave the stock ECU untouched in case I need it for whatever reason (esp. important if car is under warranty). If ECU is flashed, it may reduce resale value if buyers do not like a modified ECU.

 

Of course, piggyback or standalone, it should be plug and play with the harness so there is no need to cut wires. This will allow me to revert the car back to stock whenever I need it (just plug back original ECU).

 

Of course, there are limitations with piggybacks. AFAIK, many piggybacks do not have VVTi adjustment and boost control. Only standalone ECUs have them.

Seriously, unless there is better FC, I wouldn't bother. Cause 15hp is very minimal. You can barely feel it. You may be able to feel the "power" for a short time. Then its back to square one again.

 

ya totally agree... it is all in 1 mind....
