Wheels in Motion - Work Emotion XD9

Just wanna share this excellent video of the wheels off my ER34. I'm running Work Emotion XD9 with the below specs:-

Front: 18×8.0JJ+35 5H-114.3
Rear : 18×9.0JJ+38 5H-114.3

This video is showing the rear wheels on a dyno machine. Enjoy!

ER34 On The Dyno (again!)

Ok guys. Following up on my post here about the retune of my Power FC, here is the video of the dyno run. Sorry man, can't help but tease a bit. Hahaha

The ER34 went through more than 30 runs on the dyno machine but I've only uploaded one of the runs; well, basically they are more of less the same anyway. Is the car a tad loud?



Oh yea, there's another video where massive flames can be seen spitting out of the ER34, but I think I'll just reserve that for another day. :P

Retune of the Power FC


Pic 1: ER34 strapped on the dyno machine

After my botched up crappy tuning of the Apexi Power FC (read here), I've gone to another tuner that would at least meet my expectations and would know what he is doing. In preparation for the retune of my Power FC, a couple of items had to be done. They are:-

1) Obtain bigger cc injectors
2) Fuel pump rewiring (read here)

I got Nismo 480cc injectors for the retune but those ran out of flow. We found out the hard way while road tuning the Power FC. A good 200km of distance travelled were wasted and the tuning had to be stopped. These lovely injectors were already maxed out at 6,000rpm. Sigh....

With much hesitation, I put up the Nismo injectors for sale; and it was gone in a week! With the renewed funds, I bought bigger 650cc injectors from Sard. :)

So the ER34 were in a half state of tune for 2 weeks while I waited for the Sard injectors to arrive. No worries since I'm not going anywhere much and if I do, I never drove past 4,000rpm. Yes, this self-restriction is mighty hard to cope with. LOL :D

Anyway, with the Sard 650cc injectors, one can be assured that there would be more than enough juice for the ER34. After the injectors arrived and were fitted, the car saw another 200km of road tuning before being strapped on the dyno machine for another 100km of fine tuning.

On the rollers, the ER34 spend a good solid 2 hours plus to get the tuning right. The power and torque curve is now much smoother compared to my previous jagged edged piece of crap tune. My air fuel curve can be better but given the amount of effort spent, it's the best that my tuner can extract out of it. It’s running a tad on the rich side now.

Whilst power and torque went up, fuel consumption improved dramatically! In my previous crap tune, I got 220km out of the full tank of 65 litres. Yea, it really sucked. Felt like I'm driving a big block muscle car. WTF!

Now, I'm getting far better mileage. Still on my initial full tank of fuel, I've already clocked 300km before my refuel. And a third of it is hard runs on the dyno machine! Most definitely it will however drink like the "Thirsty Traveller" during my hill runs but that’s expected anyhow.


Pic 3: Tuning the Power FC

Preliminary feelings on the car is that it’s now much tougher to drive hard and throttle modulation is crucial during cornering lest it’ll be tailing out. I am missing my stock turbine responsiveness with its early spooling. :(

The HKS GT-RS is a responsive turbine as it spool earlier than bigger turbines like the 3037s BUT it's still a tad laggier compared to the stock snail.


But when the boost kicks in, it’s bloody frantic! The car is also spitting massive flames. Wild bonfires in the still of the night. Hahaha

I have a strong feeling that I'll be much slower when I tackle Frasiers Hill again. That has got to suck! :(

Anyone care for a video of the dyno run? Hehe :)

Dyno time for the ER34

After the 5 part Stage II entries, invariably there will have to be a dyno session to tune the ER34. Well as promised, here is the video of the ER34 being dyno-ed.



The dyno session didn't go too well or up to my expectations. If you have noticed all the time I do not name names of the workshops I go to and this is no exception even though this is a ranting blog entry.

Well, this particular place I went to dyno and tune the car is somewhat well-known in a way. Initial impression was ok as the tuner explains what he will do but he doesn't seem to ask too many questions on what I have done with the car. I do believe understanding the work done on the engine will give him a better idea during his tuning session. Oh well, so anyway, onto the rollers the ER34 went and all strapped in fine and dandy.

After the first few power runs, this is where my confidence level went from ok-not-too-bad to absolute zero. The tuner came to me a few times with his diagnosis on my car. First up, he claims my Power FC has problems, then commented that my Tomei Fuel Pressure Regulator was not setup properly, after which it was my SARD Fuel Pump that has problems, and then it was my coilpacks ...... no hang on, there is more ..... I was questioned why I used a Z32 AFM instead of the original ER34 AFM. You can imagine how frustrated I am with all this blaming game.

Of course in the end, none of the above got problem. So where or who is the problem? You be the judge.

Is that the end? No way sir.

A couple of worrisome comments were thrown in also just incase the customer (me!) is not already pissed enough. First up? SARD makes crappy fuel pumps as they tend to overheat and stop functioning after a couple of laps around Sepang International Circuit. Whaadaa! Noooooo, that's not enough; I was told to upgrade to twin external fuel pump with a 2 litre fuel surge tank. That will gain me precious horsepower. WTF right??


By now, I've already given up and just can't wait to get the tuning done and get the hell out of that place. What is more worrisome is that when I drove off I realised that the injectors are already maxed out at 100% after 5,000rpm. This can't be safe!

A call to the tuner to highlight this is pointless as he assures me that is it perfectly ok but of course upgraded injectors would be better. It is ok at 100% duty cycle at a low 5,000rpm? Gosh, makes one wonder .....

By now, you would have guessed that I have wasted a lot of time on this and also wasted precious hard earned money.

Isn’t this a WTF experience?!?!

Yes I am still fuming mad. One thing I forgot to mention is that the tuner did not tune the car from start till finish. He would do the initial tuning yes but; by the the end of the tuning session, he said, it's more or less done and ask his staff to just tidy up the maps and it's good to go. Did he bothered to come back and check? Nope, he's busy sipping tea in his office. wtf!

Oh, I was told I will be given a 50% discount when I come back and retune/adjust the maps (within like 2 weeks or something). Well, if you're reading this, you can shove the 50% discount up your arse coz even if it's free, I'm not ever coming back.

I love flames !!!

No, I don't mean flame grilled burgers but rather, exhaust flames! Check out these flames coming out from the ER34 during a dyno session. Yeeeehaaaaa.... :P

Pic 1: Flaming hot!
