Help Rb20 Mines Ecu Wont Work?

[hornby88]

Hello all i got a mines ecu from ebay japan for real cheap i thought it was worth a try to get cheap upgrade for now, the owner said it was all good etc so i installed it today got reds fuel pump came on etc but wouldnt fire just cranked constantly, could it be the ecu was for auto rb20? or could i need another crank angle sensor maybe? i havent checked if im getting spark yet but does anyone have an idea what it could be?

ive attached the photo of the ecu i bought below

cheers

Unless you got it for free it wasn't real cheap, (insert Jap tuner) chipped computers are a waste of time unless you know what its tuned for AND you've opened the cover and know whats inside it.

It looks like that part number is Auto,4WD.

You don't know what size injectors/latency and airflow meter it is setup for, if those values are different = no start

yeap, how do you know it wasn't tuned for a R33 GTR with twin T88 turbos, and NOS, that ran 7 second passes?

Mate, you got ripped off something cronic.

There is NO WAY I would EVER do this.

I don't mean to be rude but its a mines computer, that fact alone means you are a brand new owner of a paper weight.

if you did a search on these forums for "mines ecu" you'll find alot of ppl bagging them

even if u did get the car to run, thers only a slight chance the tune is going to be safe and im pretty sure those ecus dont even go into R and R if knock is detected - id choose a stock ecu over a mines ecu lol

better luck next time!

If you want to destroy your engine, by all means keep using it..

ohk fair enough cheers for replys i guess it is a paperweight then i should of checked the part number on the ecu i thought it looked different to my factory one, i just installed a r33 turbo and other goodies so i just didnt want it to lean out etc hense why i got the ecu mines are a big company in japan so i bought it i guess? i may aswell just save for power fc for rb20 then

stop wasting money. There is no need to have a powerFC

There are always pro's and con's about different ecu's. But lets not go into that here.

Choose what ever ecu u like/ can afford/ and ur tuner is good at tuning

Its because it is remapped for larger injectors and a HK gt2530 (most likely z32 afm too)

it wont work on a stock car.

throw it in the bin and get a nistune installed + tuned, you will never look back.

[bozodos]

don't throw it in the bin, sell it on ebay lol.

I had one come with my car (redundant due to RB25), and a mate had one on his RB20DET NICS, BUT it was already installed on the car from Japan, and was one of those ones set for the usual catback, removal of speed cut etc etc.

Main problem with the ebay ones is like what's been said, you often just don't know what specs or fuel they were tuned for

LOL at The Mafia <3

Nistune ittt.

don't throw it in the bin, sell it on ebay lol.

I was going to say that but it just means some other poor sap with end up with it, maybe try and sell it and specifically say you have no idea what it was tuned for, buyer beware then.

[hornby88]

yeh well the seller said it was for intercooler exhaust etc, ill just state its for auto when mine is manual
