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

Edited by aleks

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

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!

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

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 :/

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.

    • Let's hope that's not a copy pump either. There were so many copies of them back in the day.
    • Damn it, I was at work last night, and stayed in a room there during the storm with the car outside, but undercover, I just went downstairs and well....there was a large steel locker that has come from some place last night, it wasn't anywhere I could see yesterday, and yeap, it landed on the fraking car....of course it did..... LOL So, I'll need to take it back for paint and panel, luckily it was only the boot that took the hit, so it could have been worse Serves me right for staying at work and getting on the cans with some of the boys
    • Yeah, really happy with how it all turned out As for aftermarket lip, nah, I'm not really a fan for practically reasons on a street car that gets driven everywhere  I did have the full lower kit on my 2015 STI, but found the front lip scrapped alot, even at stock 4x4ish ride height As the NC sits now, with the lowest point of the car at 110mm, so just legal, some steep driveways and steep speed humps will still "just" scrap those little plastic OEM air dam thingies on the undertray just before the front wheels
    • Here's one I help build and tuned a decade ago, Garrett  GTX3071R Gen 1, T3 twin scroll 0.83 rear housing. Went from larger 272 cams down to smaller Tomei Poncams to help with the low end. S13 non VCT motor. Car was purpose built for the track, hence low down was the focus. Note the actual dyno chart shows lower boost, however the EBC and boost gauge showed 1.9Bar (Ignore the torque, I was young and didn't know how to set derived torque)  
    • I’m doing some side developments on SR20det S13 engines, its one my hobby cars used it to compare flow capacity of some smaller size wheels. SR20det is one of another JDM legendary engines I'm sure there are plenty of SR enthusiasts on this forum, I will share results some common turbo configurations here. a quick run down of what the car is: Wide body 180sx Type X with black top engine (blue). It has: Stock bottom end Haltech 1500 ECU 5-0 motorsports trigger kit Kelford SR20DET Beehive Spring with Titanium Retainers Kelford Cams SR20DET S13 188-B 268/272 Cams G25-660 Turbocharger in T2 .64 rear housing internally gated ARP Head studs MLS head gasket 1000CC ID injectors Walbro 450L Fuel pump Front mount cooler kit JJR’s 3 inches turbo back exhaust (its too short for the 180sx it had to be extended) Pump 98 fuel Hub Dyno tune So far made 270rwkws at 22psi full boost by 4500RPM. Engine is very knock limited hence a pretty bad looking top end. From previous experiences it seems like SR20dets are happier with bigger size turbine, some thing like a GT30 would make way better top end, but on same time response is lost. It won't be a problem with S15 VCT engines. I'll be testing alternative turbine housing, turbine wheel and possibly dump pipe options for extra flow to resolve the problem and of course E85 would resolve all the issues.
