Merry Xmas Black Mamba! (Part 2)

Part 2 of this Christmas shopping is the most interesting event to date for Black Mamba. After almost 2 years I finally decide to upgrade the brain of this car to the most preferred aftermarket ECU for Honda - The HONDATA!

Before I go further I would like to let you know that Mamba has been running on stock ECU for almost a year, after selling off the E-Manage Ultimate and V-Manage. The last power dynoed was 194whp and 18.6kg/m torque as opposed to 207whp and 20kg/m torque on the E & V-Manage. It was quite stressful to drive the car for almost a year in stock condition with the VTEC point at 6000rpm and 180km/h speed limiter.

Anyways, back again to the Hondata. I went to Tung Chun Motorsports JB to get a set of the Hondata K100 ECU. Considering the fact that I am not going to tune the car on my own, I decided to get K100 instead of the K-Pro. It's cheaper by almost 40% than a K-Pro and works the same way. The only downside of the K100 is that it requires a K-Pro circuit board to be put inside the ECU to allow it to be tuned. And yes, it also has no datalogging; which I dont think is important to me as a casual driver. :)

Installation was very quick and completed in matter of minutes. Tuning was then done by Ah Han and after almost 2.5 hours on the dyno and on the road, Mamba has unleashed few evil ponies and torque! Hehe. VTEC point is now lowered to 5500rpm, rev cut is raised from 8400rpm to 9200rpm, 180km/h speed limiter is removed together with optimized air, fuel and igniton. The figure on the Dynomite dyno machine was 218whp but since I do not have any baseline graph on the machine, I went to JC Racing last week to compare the old and new power. And the result after tuning? Additional 15.4whp and 1.8kg/m of torque made me drive the car like mad for almost a week! Haha.

3rd gear 140km/h ok laa kan?

The revs feel lighter, and 20.5kg/m of torque made higher gear change more fun, especially from 4th gear onwards. Fuel consumption are still maintained and I could still drive 250-270km with RM60 worth of RON97 petrol. Oh yes, the CEL error has also been deleted. The only issue I am having is the blinking immobilizer light. This is due to the immobilizer being disabled in the ECU, but the immobilizer unit is still active. Common issue for 2005 DC5 Type-R (older pre-facelift model doesn't have immobilizer). As long as it's not CEL, I'm good with it.

So that's all for 2010. Mamba is going for a hibernation until the next mod (aftermarket header and bigger exhaust pipings). Looking forward for a better and prosperous 2011.

Cost: RM2,XXX (Brand new)

Where: Tung Chun Racing, or any other Hondata distributor in KL. Price doesn't differ much.
