My 1JZ Thread - trials and Tribulations

[bobiseverywhere]

BTW I am in MN in Saint Paul right now. I brought my ECU with me so i will see if i can get it fixed while i am here as well. I want to have a working ECU for when i get back. I'll probably take the ROM board off tomorrow.

I am Impressed from my home to here only took 23 hours of strait driving

 

[suprahero]

I'd rather slice my wrists than drive twenty three hours.....................

 

[bobiseverywhere]

LOL

it wasn't to bad could have been worse but deffinatly could have been better...lol

 

[bobiseverywhere]

Well i have the rom board off and i will be back home next week sometime

PM Sent Mattjk. Just gave you the info i found about the costs. Not that it is easy to find allot of info. Allot of people give you the contacts us bit...lol

I figure i would sell it in favour of going with a Full Stnadalone that is also Plug&play while maintaining all the OEM functionality. Like the HKS V-Pro or something. I don't mind that a dealer need to program it since i dont have enough knowledge myself to do it.

either way we will see how things go

 

[bobiseverywhere]

Well i am home so i will be getting back to things

The weather is Global warming warm still here

supposed to be 11° C tomorrow and above 0° C for the next week

I am planning on selling my TECHTOM Rom board. Posting up a F/S Thread obo

 

[bobiseverywhere]

W00t

I figured i would try my ECU with out the techtom on it and No more backfiring

Just very slight small ones at 3K plus very small, not to sure why yet

No Check engine light either

I think i have a bad alternator though. The car is idling now between 300 - 500 RPM and my Alt is providing 12.5V when i get it up to 1K then i see 14V from my Alt.

 

[bobiseverywhere]

its almost like it wants to stall but it won't

 

[bobiseverywhere]

I am at a loss now

When i started the car up everything was perfect no backfire, idle was dead on and 14.3V from the Alt, I have a Apexi TT When i went to turn the car off, the timer just shut off right away instead of letting the car idle, it is set for a specific time ????

Then i tried starting the car again, Bad idle, low voltage, Backfiring/missing a bit when revving above 2K?????????????

Checked the ECU again still just the one Blown Capacitor.

i am at a bit of a loss on this one. It works and runs perfectly then shut it off, start it up again, then it does not run right???

 

[suprahero]

Damnit Man!!!!!!! I was so hoping that yours would go smoothly, and give me a sense of false hope. Hopefully someone on here will bail you out. I know Aaron is online right now, so maybe he can help you figure this one out. Good luck brother...............lol

 

[bobiseverywhere]

For the most part it has not gone that rough, i am very thankful for that.

Keep your hopes up i think you won't have to many issues. I think you have a better starting point then i did on my build Jay

i forget are you getting a stand alone or are you keeping the stock ECU and using some piggy backs.

Mattjk suggests having all the capacitors changed, it is a very good idea. A TV Repaire shop should be able to do it no problem.

 

[bobiseverywhere]

i updated my running total on the First post if anyone is curious of the cost so far

 

[Quin]

I just read all 42 pages of this... yay! lol Did you get your idling problem fixed yet? 2jz alts are the direct replacements I think. How much do TV repair shops to swap your caps out? I can do it, and I'd be willing to do it for like shipping and maybe a dollar for a coke or something

 

[bobiseverywhere]

I am getting the ECU Fixed this weekend, so i will let you know probably next weekend if all is fixed with idling and alt regulation

The Alternator for a 93-94 Lexus SC300 is a perfect match and is higher amperage i belive. it has been said it's only $100 at the dealer!

i have been stalled for a bit on this.

thnx for taking the time to read through everything. i have nto had a chance yet but i am going to put together a resourse site of sorts for 1Jz instals for guy like me with still beginer knowledge

 

[Quin]

I remember that now, 110 amp instead of 100 I believe. Lifetime warranty too.

EDIT: Doesn't the SC300 have a 2jzge?

 

[bobiseverywhere]

small update

i got lucky on the ECU repair. My step-fathers friend at work said he could do the work on the board. The guy normally Builds / Solders, repairs and installs Cuircut boards for Jet Aircraft at bombardier and has been doing it for 35 years I think he knows what he's doing.

I can't wait to test out the ECU and see how everything is running. I'm pretty sure that all will be good after this is done. :biglaugh:

 

[bobiseverywhere]

I remember that now, 110 amp instead of 100 I believe. Lifetime warranty too.

yup thats sound right. I personally like the life time warranty part can't beat that really. buy one and if it ever goes bad again get another free or fixed ASAP

 

[Quin]

I made an estimated price list for mine today, not counting a boost gauge, BOV and the 550cc injectors w/ Walbro (wants) it came to $3390 USD. Everything but the engine was off of DM. I guesstimated the shipping but I think I was conservative.

EDIT: Yeah lifetime warranty ftw

 

[bobiseverywhere]

i replied to your PM hope it was not to long. it is always good to estimate your costs. Don't forget vital fluids.

Just make sure you add an extra $1000 to what you are doing. It always adds up fast for just the litthe things here and there

 

[Quin]

Extra $1000 lol I replied to your PM, it was very helpful

 

[bobiseverywhere]

Well i The Guy working on my ECU finally had some time to look at it. Found out i had a whole bunch of dead Capacitors :biglaugh: There were a bunch that just have not spewed their contents onto the board

Anyways i should have it back next weekend

Then i finally can get some vids in. If the roads are clear i'll take it for a spin
