the love hate relationship

yesterday, driving around with Megat's ECU that i borrow earlier, not much a different compare to mine,engine revving stall at 3000-4000 rpm and cant reach full boost~like something holding it back..not to mention high consumption of fuel huhu

the next day, i bring the car over to Jepp's hill garage place,seeking his help and advice,after changing another set of plug,the result is still the same,then Jepp told me to check Map sensor. since joe40c already relocated most of the things inside the car, i found out the air hose connected to the Map sensor is struck between fuse box igniter, cable and wire,

guess i overlooked it when uninstalling the glove box to reach for the ECU

(FIY jzx81 ECU is located inside the dashboard,above the glove box)

fix it up and BAM! its all good and back to normal haha =P

i tell ya,3 years and this car have never failed to surprise me~

im learning new things every freaking time...

hence,i still love it! because i rebuild it from scratch =)

i always tell myself, i suck at fixing things but sometimes i think i did a good job~LOL!

a month and a half

still not running & what a waste of my roadtax...

did u know the roadtax for 2500cc vehicle in Boleh Land is rm870 per year,

can't afford for a year,so i opted for 6 month only...

no luck repairing the ECU, maybe have to find another set~

God knows how i hate jzx81 ECU!! LoL

part 2: Biggie and Pac?

just as i suspected,a fry capacitor!~

ask my dad to help me repaired the ECU,plug in back,and start..idling went wacko~

i already pull out the battery terminal to reset the ECU setting,also wanna change the spark plug but then again~its sunday!!all the shop are closed beside raining cat n dog just isn't helping..

i hope that will settle the idling issue,

honestly im on my last nerves with the stock jzx81 ECU..

after the single turbo conversion is done,im definitely gonna save me some money again and buy me a stand alone management (within another 4 year maybe hahaha)

Biggie and Pac?

i supposed to change the rear suspension back to JIC yesterday..i drove all the way to pick it up from my parent home in Kajang to my place in KL..removed the kit,backseat,jack up the car only to discover i didn't have enough tools..maaaaderrfarker!

considering that i have to work at 6pm (take note its Sunday...urgh) i postponed it till next week,packed up and start the car,guess what..it wont start..after checking all the necessary thing,

i try again..everything was okay,it start ok~then i noticed the "engine check light" went blinking on and off a couple of time..5 minute running,engine went into subaru imprezza version 8 boxer mode and revving stuck at 2000rpm...later it when dead again for good..

haven't got a decent time to properly check the problem and Joe40c will be coming tomorrow~

i have a feeling that its the ECU..we'll see if im right or wrong hahaha

Inside a Blitz

got this jza70/jzx81 ecu that was sent to me for repair

it looks like it got an extra board compared to the stock one hmmmm~

brain surgery~

when my dad isn't busy,he help repair my friends x8/a70 ECU

back up have arrived..

trying to solve the engine problem again....

got this 2nd hand Denso Iridium Spark Plugs...thanks to Za

also i went to Ampang to borrow this..

ooo its look like The Factory Joker have a secret...

this actually came along when Aim bought it..no wonder the ECU got unstable revving hehe....too bad there is no capable tuner for F-con here in boleh land...

so i change the plug and put in Aim ECU...at first it started running okay..then after a few minute,it happen again...1 or 2 piston isnt working correctly...so i suspected it wasn't the ECU problem...but the check light warning appeared...isk

i met a dead end for today..called a few 1jz owners,and ask them about their opinion and they suggested,try changing the igniter first..and if that didn't work..i might have to sent it for a check up using a diagnose machine..so tomorrow i will borrow the igniter from Aim..till then....huhuhu

aaaaa not again...

the "boxer" engine symptoms return.. one or two piston is not running...also spotted some spark on the no 3 coil pack,leak maybe?? i switch the coil pack up,still the same...also i took out the ECU and change one of the capacitor that i bought before..haven't got a chance to test it up..been busy with working and its been raining almost every evening...

missing pieces of the puzzle..

Rs Component ordered it directly from Nichicon Japan...25pc of 15uF 63V capacitor...since i cant find the 35V, this will do..

so here's the deal, if any of u got a faulty 1jz ECU and wanted to repair it,i can do it for u for only RM50...i did a survey,most of the shop will charge it at the minimum price of RM100...the catch is there is no warranty and i only change 5 of the favorite fried capacitor...(offer stand in Malaysia only hehe)

interested plz sms/call me 012-6680474 Azrin

p/s:this is more of a helping hand rather than making profit ;)

From Rs Component

got it today through courier..

good service..i highly recommended it hehe

but...

i fucking mistakenly order the wrong set !@#$% rm17 wasted...huhu

here is the right one

anyway i re-order the capacitor...hope to be getting the right one soon...

DIY ECU Aftermath..

here is the f*ck up capacitor that been making the engine gone insane..

the red circle is the new replaced capacitor and see the rusted board due to the fried capacitor (yellow arrow)

my dad didn't manage to find a replacement for this 15uF 35v capacitor..so he said to just use it first,if still a problem with the ECU,then we will know the source of it..by the way i found out that there a company called RS-Component Malaysia,located in Shah Alam have the exact capacitor that im looking for..thanks to "Google" hahaha...will gave them a call on Monday..

also bought a spare capacitor just in case hehe..

so i went home,connect the wiring,and crank it up...nothing..connect the cable and jump the battery..still nothing..replaced thebattery with the other set...and with just one crank the engine started!!the old battery was dead..

Ipin and i noticed the engine idling is lower than before...around 500rpm,so we adjust it a little higher and we go for a run around the place just to check if the problem is still there...

after of almost an hour of smooth driving,we concluded that the ECU is fixed!haha no more jerking,no more flooded spark plug hahaha

unlike before, i hate driving with the a/c on becoz the idling is quite high,even after we adjust it,now its just comforting hehe...damn,capacitor really play an important roll on the engine behaviour...

many-many thanks to my dad,who repaired the ECU with the cheapest cost ever!

next up oil change,new spark plug and the most important....servicing the twin turbo...

heavy smoke like the car is on fire...errr i cant drive like this

also i need to replaced my dad battery,coz i took it out from his car hahaha..

will Fix it..

the bad news,here is my fucked up ECU..

to have someone that is capable of repairing electronic things in the family is always a good news(it can saved alot of money as well)..my dad,he used to be an electric technician..so changing a few fried capacitor,isn't too much a problem for him..plus he will checked all the capacitor to make sure everything is okay...

here is a good link on what capacitor that need to be changed..u can even DIY hahaha

hopefully it can be done by next week..insyallah

i miss driving the car already huhu

shit just got worst everytime...

on fine Sunday afternoon, i decided to sent the car to the workshop to install the fuel regulator and internal fuel pump..at first everything alright...then it breakdown in the middle of the highway...

waiting for the tow truck to come..

i was escorted by the freedoms crew (lan n Ipin) and Ajis (Ipin older bro) with his bosuzoku Bmw..

30 minute later the tow truck come,lan helping me with the loading and were off to setapak..

thanks to Bob towing service and rm170 flew away from my pocket hahaha?...

upon arrival,Shahrul (the mechanic) remove the tank and the external fuel pump..

my bosch external fuel pump,still can be used...will keep it just in-case if i decided to use a surge tank..

i also in need of the digital float..(*that is the stock float in the pic..currently still searching for the digital one huhu).since i dont know how much fuel left in my tank..

we supposed to install the works fuel regulator as well but we got the wrong set of adapter...

upon starting the car,the problem of overflowing fuel on injector 3 & 5 happen again.. the engine combustion isn't nice till the exhaust squirting unburnt fuel through the smoke.. shahrul begin diagnosis all the possibilities like the coil pack, injector, spark plug, fuel line and he even done the compression test (all in good condition)...he conclude that the problem might be the faulty ECU.. luckily Koopang was around with his car, so i borrow his car ECU and put it into mine and it work just fine..*sigh....another parts that need to be replace,aside from the turbo...

i also test Aim spare ECU,called The Factory Jokers..its kinda special becoz the ECU got some external black box and it have been tuned by the japanese for track used (there was a sticker saying it so)..the noticeable different reaction when the engine start is the idling, revving automatically when up and down from 1000rpm till 1500rpm (like it got a high-cam) but once i step on the gas pedal the revving easily reaching 5500rpm,very light...

but it was nothing like that when on Aim car,the idling maintain at 3000rpm and when we installed it to koopang car the idling set nicely at 500rpm... so i assumed that the ECU characteristic/reaction is totally different on other cars...

the time was already 11.30p.m, im getting tired so i install back my faulty ECU and went back home...just when im reaching home,the car when into another breakdown.....causing it to be tow once again....twice in one day....i should have borrow Aim ECU that time..

arrived home around 12.30a.m,unloading the car,park it at the usual spot,lock the door and i didnt even bother thinking about it.sooo sleepy..go for a drink with lan and ipin...and went straight to bed... still have to work the next day...

also

the gtr fiber lips got damage during towing..but nothing that couldn't be fixed hehe..Bob the tow truck guy said that he have towed several X8 but none of it is slammed like this....hahaha i guess i take it as compliment...

so at the moment i will put on hold all Jyu progress,becoz i ran out of my budget,(repairing the ECU and turbo will definitely not cheap), im currently busy with worked, and next week im starting my job on a new work place...huhuhu its pretty messed up right now...sigh...

Fry Bye...

looks like were not the only one who have problem with the jzx81 Ecu....

taken from Tezuka Blog,he mention that the owner of this jzx81 mark II is participating in a drift event, when suddenly the engine just when dead..suspected a fried computer box...huhuhu
