On paper, it looks very good. Supports closed-loop fuel calibration.

Wat do ppl mean y closed loop ah??

chinkw2 · 05-11-2005, 08:40 PM

closed loop is more using sensor feedback is open loop more using Throttle Position Sensor to tuning your ECu. Am I right every advance users, if wrong pls correct me...
Thanks....

Closed-loop, the ECU continuously adjust air-fuel ratio (without using values in the fuel maps) based on O2 sensor feedback. Very useful for fuel economy, especially when driving at part-throttle (eg highway driving), but well-tuned maps can also give reasonable fuel economy.

Open-loop, the ECU ignores O2 sensor feedback, it uses values (or injector timing) from fuel maps, no processing is done, it's merely lookup, normally used when throttle is at least 2/3 opened (in systems having both closed-loop and open-loop mode).

Older engines (eg L2 or VR4 i guess) only have open-loop mode.

Is this piggyback can tune fuel and ignition indepently 100%?

YES IT CAN, IT HAS MORE FEATURES COMPARED TO EMANAGE AND ALMOST A STANDALONE SYSTEM.....PM ME IF YOU INTERESTED, I CAN RECOMMEND YOU A WORKSHOP TO TEST DRIVE OBIT FITTED VEHICLE IN PJ

In what car is that? na or turbo? pm me your no, we can arrange time than...

ok guys and gals interested in instaliing OBIT piggyback, my 2 cents of advice is test drive a car with OBIT first then decide, also experience of tuner is very important. If have the same model as the car you currently drive even better. Well thats for any other aftermarket ECU as well, not only OBIT. If the mechanic you approach like to give excuses when you request for test drive, then better be extra careful.

You can contact Gerard Draeger Racing, he has succesfully developed supercharger kits for the Satria GTI and coming up with new kits for other proton models. I believe he already got some supercharged protons fitted with OBIT. Give Gerard a call tell him Sazali recomend you, he'll arrange to have a test drive soon. His hp 0123073928. Btw I dont make any money recommending you, I'm just helping a friend... can assure you'll fall in love with his SCed GTI...

Have fun

Pricing here is Singapore is SGD950 about MYR2185. Gecko Workshop in JB have installed it on a Gen2(Siemens VDO), though I have not personally test driven it yet. OBIT is still quite new in Msia, but it's been around for about 2-3 years in Singapore and have been installed in BMWs running Siemens ECU, latest one being the M3. See the links below for more details;

The general feedback from a few users here is that lower end torque has especially improved through shifting the torque curves lower for maximum torque at 2.5 k i/o 4-5k rpm. Like I mentioned above, test drive first then decide, better if you can get the same car as your ride..thats my $0..02

Taqu,
When you mean O2 sensor is the sensor placed at air flow? So basically closed loop is MAP system and open-loop is MAF system? Can explain further on this?
