Hi this review is based on Makku's ECU chipping service. I contacted Makku about helping to chip my ECU. My engine is a JDM D15B VTEC and I had a P06 ECU. I live in Canada so I wouldn't think Makku would want to do it for someone that far but he did. Great guy, easy to talk to and everything worked out great.

Got the ECU back and had two chips come along with it. One stock P08 chip, and one modified chip. Today I idled it for the first time with the Mod chip and it's the s**t :werd: I haven't tested driving yet, but I imagine it would kickass also.

He did a great job, and nice solderng job too. Would work with him again in the future if needed. Great job Makku and keep up the great work! Nice prices too. If you need your ECU done, get Makku to do it.

When everyone in Canada didn't want to do my ECU cuz its a automatic, Makku did!

Now on to some pictures.

yes! :TU: thanks for the kind words. I am glad it didn't throw any codes... I was pretty sure it was good, but this is my first time dealing with an auto.

Those pics make everything look nice :)

BTW, I don't know if you noticed, but in the pic that shows the whole circuit board, there is a row of 3 tall transistors on the left side towards the back. The 3rd one in back was the one I added for the VTEC conversion. Plus a few little things around it.

Heh. Cool thanks for the info. I compared the old vs the new and saw new things that were put in, I just didn't know what was done to enable VTEC. Now I know! Whew. Makku is the ECU King! ;-)

I have a D15B VTEC w/ a P28 ECU. I dont know much about the whole ECU 'chipping' thing. So what can you do with my P28 to enhance the performance of my D15B?

well let me preface this by saying: No one has done a side-by-side comparison on a dyno of the p28 vs a p08 on a d15b.

BUT, the p08 has different fuel and ignition maps than a p28. I'm running the p08 maps on my converted pr4 ecu. It feels great, but I've never tried a p28 either.

So it's your call whether on not you want to try out some p08 maps on your engine. However, I can hook you up with some datalogging hardware so you can eventually tune your car using uberdata or Chrome (and a wide-band o2 sensor).

Also, if you want to experiment with different name-brand chips (Mugen, etc), you have to get your ECU setup like the one above.

Here's the thing. I have no idea what is best as far as fuel maps and such. I had a chipped P28 before and the VTEC was @ 6K, redline was @ 9K. I had no clue what I was buying, all I know was that I need a P28 to get my car running. And once I drove it, it was quick! I sold that ECU and bought a stock P28. But the car feels so slow. It doesnt rev as fast as the other ECU.

here's the thing...

those so-called "performance" chips basically have maps that are tuned on a car with a certain modified setup. For example, a true Mugen chip would most likely be the ideal tune on a car outfitted with all the Mugen crap... intake,exhaust,headers,maybe a cam, etc. They put the car on the dyno before and after the chip and show... "look! the car got 10 more hp!".

Will that happen to you if you install their chip? Most likely no. Will you get some performance boost? Maybe. But, it certainly isn't tuned for your particular setup. All headers and intakes are different. You might even be getting less horsepower over a particular range. It's up to chance. What will most certainly happen, is you will waste more fuel. Because the majority of "performance" chips just have increased fuel over the whole map. Maybe even ignition advance (might cause some detonation if you're not careful). The most notable effect to ricers, of course, is the increased rev limit. Sure, some setups need it but most do not. But it's an actual visual difference.

So here's the deal. If you want, I can supply you with a stock d15b chip. The way the ecu chipping works, is that it's completely reversible. You remove one jumper and it's back to stock. So you can test between the p28 and p08 maps. I can also set your rev limit to whatever you want. I can remove your speed governor. I can also set your vtec point to whatever you want. I can also provide a 2nd chip with any other program you want... I could try to find a commercial ROM (there are some floating around). Or I could just increase your fuel values across the board by 3% or so. This might help (more air from free flowing intake/header/exhaust requires more fuel)... or it may just waste a little more fuel.

It's your call... I can't tune the car in person. So, you either have to take a chance or pay $$$ for a dyno guy to tune it for you.

Makku heres a little tip. Take the zif and make a riser for it. Two, one stacked ontop of the other then make a cutout on the top ECU cover. This will enable you to change chips without removing the cover. Here's how mine is setup. Works like a charm! Click the image for a larger view.

hey, that's pretty cool. wouldn't have to shave the side of the zif socket to get it to fit either. Nice job!

But I'd be a little worried about static electricity though. Might want to rig a plastic fliptop over that thing.

It wouldn't work well with the RTP board I'm making though. ;)

hey makku you got any experience with the ecu's for the d17? i think it is obdIII

can't do anything with obd3... yet..

but since nobody really did anything with obd2, I doubt there will be obd3 hacks.

The only easily modifiable ECUs are obd0 and obd1 ecus.

no complaints here :)

You still never told me how it drove... only that it idled well.

Hey Makku,
Can you take Bizzar's idea a step further (an excellent idea BTW because I'm tired of unhooking everything to re-chip)

Take this $9 cable from http://www.moates.net/product_info.php?cPath=24&products_id=64 and solder a zif socket on the other end. Then run the cable with the zif to the glove box or something like that so you can change tunes from there. I may try this myself when I have more time.
Just throwing ideas out there...
