The 1jz ecu shortage

[Jaguar]

What happened to regular old jza70 ecus? I loaned mine to Clint in AZ, and as I plan getting my car to run, I kinda need one. So I can either jack Clint (and he's left trying to find one), or I can find another one for him, for me, for someone. :1zhelp:

All I can find are Mine's ECUs which are a little pricey for my tastes. I mean, $500 is more than halfway to a Stinger.

Are Mine's and standalone my only hope?

Try being an auto guy and finding an ECU....

I agree with you on the price for upgraded units, the Stinger is starting to look more and more like the best way to go.

Man!!! i got 3 burned ecus & my friend might be able to fixed them, he already repairs dsm ecus, trust me... he is the best at those.. the only problem i'll have is how to try them, i have a AEM ems on my supra & the car is not running either cause of rod knock. if anybody near chicago with a running 1jz can help let me know.

i lucked out and found my Mines for $250. but it took 2 months to get it, got it off yahoo japan. but ya, pickens are pretty slim lately, havent seen any stock ecu's for a while now.

heres a blitz access ecu on yahoo japan, youd have to sign up with rinkya and i believe they have a fast form of shipping, and its only $166

This has been happening for a while. 1J ECUs have never really been all that plentiful. The supply has gone down, sure enough but the demand has increased by a significant amount more IMO.

Buy a 2J jumper harness and switch to the Aristo ECU. Plenty of them floating around, they are cheap, and they are mapped for 440cc injectors so you can run larger injectors on a single without having to pull alot of fuel which can negatively impact your timing.

I was thinking about that! Is there any drawback to using an Aristo ecu on a stock 1j?

I am very interested in this option, where can I buy one of these jumper harnesses?

Second that!!

6700 revlimiter

The harness is the same jumper harness that you use if you run an AEM on a 1J. But yeah, the rev limit will hurt the top end pull especially if you have cams. If the cams are stock, I dont think they make power above that range anyways.

This guy is also making harnesses

You will have to add 3 injector wires to convert to sequential injection to run a 2jz ecu. But I did this on my old 2jz car (using a 1jz harness). Worked flawlessly with the aristo ecu.

Or just go standalone.

Wish I could, but not on a college budget.

any instructions on how to do this?

 

[OneJSupra]

that's why i'll never let go of my spare working jza70 ecu that bigaaron repaired unless of course someone offer me $500 for it :evil2:

refer to the aristo ecu pinout and you'll see that it has 6 pins for the injectors, compared to the 1JZ's 3 pins. for example, on the 1JZ, injectors #1 and #4 share a wire going to the ecu. that means you have to run a wire from injector number 4 to the appropriate pin on the 2JZ ecu. basically each injector has its own ground wire to the ecu.

 

[garagefujimoto]

I'd bring a few spares in from overseas, but I am not gonna waste my time and then get offered $125 for them

 

[OneJArpus]

whats wrong with the UPGRADED ecu's or stand alone prices?

prices i've seen. Not too bad. Some times you can find an upgraded unit for 400/450.

250 for regular ECU
500 for an upgraded unit (Mines, Blitz, Sard)
800 for Stinger ECU + 200 harness + 200 02
