Dyno Tuning

[aEROz]

Hi guys,

Here's my experience last weeked :

Took my car to sunway for a SAFC dyno tune last weekend. Initially wanted to go DMT but they've already closed down, so I went over to GT and got quoted RM3xx+ for both installation and dyno tuning. Went to N1 since my fren zero4 was there. Then I mai ask them and Melissa spoke to me and quoted me RM200.

Of course, I've heard of N1 stories but since there's such a huge diff in price I decided to go for it. After all, my stock 0.6bar engine wouldnt blow that easily right? Right. The workers there were preparing and strapping my car, getting the fan ready, etc.

After Desmond came back from the proton carnival in sepang he proceeded to 'tune' my SAFC. Barely minutes later, one of the rear belts snapped. Luckily the other one was still attached so it didn't hit the wall or anything. Actually, it turns out that my tow hook snapped instead. Got an explanation from them saying that it's the rust that causes it to break off from the chassis. They offer to weld it back for me.

After all that explanations and stuff they said they could hook it up to my chassis (cross member i think, didnt really notice where). So I said ok. Then Mr Desmond start to do his stuff and I just watched. Revved my car, tinker abit with the SAFC, got down and tinker with the PC and repeat. He did a few runs, 4-5 runs, and thats it.

They only attached a sensor into my exhaust and some grounding on my engine bay I think. Is that an accurate way of looking at the AFR? Hmmm. How does a wideband sensor looks like? Anyway the printer was kinda trashed... it printed everything fine but the HP and torque figure below was barely noticable. Will be collecting another copy from them soon, prob get the file as well if I could.

Stay tune for part 2...

waa snapped
consider lucky if the car not swerve when blasting time
or else may death also can happen

 

[GT20v]

aeroz,

yes,dyno tune need 2 or best 3 equipment..

Wideband sensor(stuff at ur exhaust but bcareful it has a lifespan)
Exhaust Temp(not exactly needed)
TUNER(the most important factor)


they shud do a benchmark dyno....then dyno it n tune it and then last dyno for comparison......

 

[aEROz]

cmng, yeah! Didn't really thought it'd snap. Guess the car's really too old already. It didn't really shake violently when the tow hook snapped. Just about slightly off the rails, thats all. Anyway it's still scary. Cant imagine smashing my car into the wall or the fan in front. :(

GT20v, They did a benchmark dyno but from what I saw, BEFORE and AFTER the DYNOTUNE I didnt notice much difference, the most was around 2-3hp. The tuner wasn't telling me what he's doing and stuff, which I think he should. The sensor he stuck onto the exhaust could most probably be the wideband sensor. Havent seen one IRL before actually, hehe.

Anyway here's PART 2:

After all the tunings and stuff and when I got my car back, I couldn't feel much difference. It still didn't cure the jerk I had when I lift the throttle from 1-2% to 0%. Hmmm. Maybe a little. Anyway, powerband seems to be A LITTLE smoother towards 7000rpm. I think the power that drops off after around 6000rpm isn't that obvious anymore. It's as if there's a slightly a little more power above around 5800rpm. Don't know for sure, maybe it's just all the pshycological thing. Car's too slow to notice any improvements.

AFR at 3,4,5,6k rpm is around 12:1 slowly curving unevenly towards 11:1 at 6k rpm. I wonder why 7000rpm is not in the graph since the rev cuts at around 7300rpm? Hmmm. Overall, abit dissapointed la to have spent RM800 for everything but not gaining much.

 

[GT20v]

800??maybe add a little bit more

should just go and buy SMT5 from Gt auto...a proper piggyback...

I've always felt that doin a dyno is essentially a waste of money since most of the guys that provide the service here would just hook your car up...plug in whatever is needed...run the car and pass you your sheet with little to no explanation unless you ask...you just stand by the side and ponder on whats goin on....best of all...you dun ask...they just buat bodoh....sianzzz

My 2 cents la....


Hey Mr Zul....apa khabar? :D

 

[yolk]

Master D,
wahahahhah you appear again after MIA so long ka ??

so far i went DMT to dyno got no problems that you mentioned .. but i just dyno la never tune or anything coz still only using stock ecu .. for me i go dyno just to set a baseline and most importantly to know the AFR .. coz need wideband o2 sensor to check the AFR .. other than that the numbers hp/torque not really that important la to me ... B)

 

[aEROz]

Master D, I agree. They could've at least do some proper explanation on what are they doing to our beloved car instead of 'just doing their stuff'. And the way they strap the car is just not good enough. Just four simple belts attached to the floor. And the clearance of the workshop is not good enough as well. There's a car infront of me, a PC on the left, and a toilet on the right. Aaaaaack!

GT20v, actually, RM600 for the unit and another 200 for the tuning. How much to tune the SMT5 at GT? I wanted to go to GT initially but their price is a very big difference compare to what I paid....

yolk, heard anything about DMT re-opening again anytime soon? How much did you paid for your DYNO run?

So I was thinking, RM800 for some fancy blue screen, this is not right. I want to stop spending all my money on cars. I want to, but I cant. It's too addictive. Damn it. I think I should get an adjustable fuel pressure regulator and a boost controller to up my *"very conservative boost" next.

That should be enough to beat my brother's 3S. Ha!

p/s: * - according to the tuner

 

[GT20v]

master d is right......so its best you learn or bring a friend.........but dun bring too many sifuuu.......nanti we all better than him and start bising2 hahhaha


wassup MasterD,hows 4agze????? :D

 

[GT20v]

DMT reopening soon..under new name and management..thats the new owner told me lah..........hehehhehe
anyway GT auto i heard is good in tuning....u pay for the expertise..i guess

 

[BLaCkHoWLiNG]

yeah...dyno is a waste of time.. pple invest 100 of thousand on dyno machine jes to take 100 - 200 bucks from u.. print out a lousy 20cent piece of A4 size paper to shit on yer day by saying u got 2-3hp gains..

driver feel and butt dyno is d best!

so dont waste time on latest technologies and stick to the old days of your asses

 

[seperlinky]

how you know.. who said one? =)

 

[BLaCkHoWLiNG]

Lotsa occasions whereby it's not the tools of trade that's really important.. but the pple behind the tools of trade... If i pass a ferrari to an auntie and ask her to go 1-2 laps in SIC, i bet Zul can pass her twice before she can finish a lap...

Dyno machines are there to paint reality to u... what and how yer car engine behaves and how much power it can produce... the tuner, has
to know precisely what's he doing... not jes tekan tekan. picit picit
with the device and "pay up!! so long motherfucker!!"

It's really funny d way i read it, he hooked up the sensors during the
finishing stages of the dyno??? hmm... even in 'some other places'..
d dude who was dyno tuning an L2 kancil, was using 5th gear.. gosh!
dat's disastrous if u ask me...

Btw, with an SAFC alone, u cant expect much.. it's jes only fuelling...
but i did hear and see a 4AGZE gained 12.5hp jes from dyno tuning
via SAFC in Speedworks..

 

[Master D]

aEROz Shit happens dude, I guees you should be thankful that the car is not damaged in anyway after the tie hook mishap. I do agree with Zul, bringin a fren would have been better...if he was knowledgeable, at least can help as questions or stuff, if he aint knowledgeable, at least you have someone to b1tch to on the drive home :D At least you have a new blue screen to stare at now.... :P

GT20v Hey man....yeah lama MIA, I'm in JB now la,...moved here a year ago. I'm back in KL abt once a month, hope to meet up with you guys sometime soon. Car is fine, finally painted..hehe no more kurap on the hood.

:)

 

[Master D]

Yolk,

Hey man...how are you...heard you have a BT now? Terror ar!!!!!! :D When do I get to feel the speed of a BT!?

 

[Master D]

Btw, with an SAFC alone, u cant expect much.. it's jes only fuelling...
but i did hear and see a 4AGZE gained 12.5hp jes from dyno tuning
via SAFC in Speedworks..

wow...now this i wanna try....Speedworks still open in KL? Where is the location ar!? :D :D :D :D :lol:

 

[BLaCkHoWLiNG]

mauhahah... dun waste yer time.. i tried it.. gained 1.2 hp

 

[Master D]

seeeee.....these kinda things too damn good to be true la....want more power...buy the real thing....ehhh blacky!???? :D :D ;)

 

[aEROz]

Master D, I actually brought a friend along, but he has some other happening places to go mar so the end lor. He's very nice lar, accompany me from 4 something till 6 something. Even my I-sleep-18hours-a-day-brother wouldnt do that. Hahaha :lol: Anyway I wont be displaying my SAFC with all the breaking-in and stuff happening lately. I'll lock it up someplace safe. Hehehe

Anyway thanks bryan my man. Waiting for your response and bring me and drag with your hoooondah. Hee hee hee.

BLaCkHoWLiNG, Wah, 12.5hp gain from dynotuning a SAFC? Serious? Then I should go back and get my refund la hehehe. Erk... i didn't mention anything about them plugging the sensor at the finishing stages ma. Sorry ar my english not good so I didnt do a proper explanation hehehehe. Learn my lesson already lor. At least I get a A4 paper with some fancy graphs and number on it ma hehehe. Maybe when the new DMT reopens with their -buy-this-free-dyno- offer I'll go and do summore dynoes heeeeee hee heeeeeeeeeeee.
