I put the laptop on it the other day and my mate brought up his little diagnostics program at the moment it seems to be that the tps isn't staying in closed loop when you release the throttle which is not activating the icv to remain idle after the revs come down. I got told by someone that a 20 tps was the same, well not the redtop one anyway tried that last night. New wheels are on, so's the r31house strut brace. On the look out for some blue 33 seats if anyone has any?

Errr cheers for the link saved it. Homeboy who wired it will bell me after work I'll ask him if he kept the consult in the wiring assuming he did and whether it would work with the check engine light on the dash of the 31. I thought they had an led on the side of the ecu that flashed. And to the reg fair enough, I saw that it was about $100 to buy an inline efi gauge or $199 for a regulator with a gauge so I was going to buy the reg with gauge. I'll see if I can get the diagnostics checked out n see what it says. If it doesn't work on the dash can I plug an ODBII reader into it anywhere? I know my friend owns one.

Thanks WMDC I'll have a look bud. RB25 series 1 stock ecu and loom has knock sensors installed I'm assuming they're 25 to match the ecu? I have sexy fingers when it comes to electrics so the boys sorted it out for me. Running stock fuel pressure reg at the moment waiting til pay day to buy a nismo non rising rate set n forget incase the 040's pushing past the stock regulator. All my diagnostic stuff is for carby so can't check the fuel pressure yet. disconnected the 02 sensor and just had it stationary and it was doing all the same things, will it be different under load?

The rb20 stopped fueling all of a sudden had pressure at the rail had signal going to the injectors but the injectors would pulse random amounts at different injectors and not in sequence. Tried 3 differents AFMs Tried 2 different ECU's All sensors are RB25. How do I do an ecu diagnostic?

In perth 40km's from the closest tuner don't wanna drive it don't really want it to be trailered and left at a shop with an open bill. Rb25 only went in it after a 20 had spent 4 months at a professional shop that couldn't get it running. And I was left with the bill. I'm running out of money, I'm running out of patience and a shop is a last resort but I was just wanting a bit of a checklist to try from home.

Hey guys thought I'd put up a thread for my 31. I bought it as a run around when my 180b did it's rings in usual story though I can't leave anything alone. So another story of lots of money lots of tears and my usual sexy fingers being upto no good! I bought it as a dirty 30 with some bling blang 18's on it for about half the price they wanted. It was well rockingham spec with upside down southern cross's and such is life stickers to boot. First I just tidied it up put a cd player and some splits in it, passage rear set , muffler and some panasports. I then bought another 31 with a manual box 1 piece tailshaft rb20 etc etc that had been nicked and semi parted out. Didn't work out as well as hoped but hey! I did alright. At first I started with suspension and changed the wheels on it. (wheel whore warning) I put a set of KTS teir III's and SR turbo front suspension set up in it thanks to mayhem and my old SSR Formula mesh wheels on it. I drove it like this for a week, it was the bomb! Auto, na didn't matter 10s/8s it slided so well seeing as the diff was that bad it would bottom out in the cash n spin both 70% of the time. Unfortunately I only got to drive it like this for a week and then stupidly decided to pull the motor out. Because all my mates had told me it's a weekend job to pu a 20 in a 31. A mate and I had it in and manual in 2 days. The afm had been cut off the loom so I rewired that in, it was running nistune with a z32 afm. I finally got it to sort of run and had a bad vac leak wouldn't rev up or go well under load etc. and it looked like this for a while because all my friends were all of a sudden busy while I had the first car I'd ever owned that ran efi getting electrical issues. Lots of sleepless nights lots of anger. After a few months I'd hate a bloke do some cashy electrical work on it and I got to the point where I'd booked an appointment with Andrew from hyperdrive. So i finished cleaning a lot of stuff up on it and gave it to him. Really lucky he didn't see what it used to look like as I'd cleaned up a lot and he was overwhelmed by the 31 dodgeyness. This is the day it went to to Andrew, he spent a couple of hours that afternoon on it and had told me to come pick it up. I got the and he'd limited it to 4500 rpm because it was running lean above that no matter how much fuel he told the computer to throw at it. It was still making 160rwhp on 10 psi at 4500. That 20's a good motor.... I get out the driveway and bang it drops cylinders. Had to push it back into the carpark and that was the last time that 20 ever ran. 2 looms, 3 afms, 2 cas's , 3 ecu's and 3.5 months later I was left with a bill no running car and a decision to make. This was the day I put on the trailer, I got told a couple k for a custom loom and computer and it would get the 20 sorted or put something newer in. I got a score of nick picking up the 25 for a very nice number with low kms on it. So i towed it to my mates who lived around the corner from the shop as Andrew was going to wire it. we got the 25 in! after it turned out the clutch was gone, the radiator hoses needed replacing and a few other things that slowed down the once again two day job to about three-four weeks. Then Andrew was busy and booked out for a while I had a mate modify me a custom loom cutting out everything not neccesary and looked farking smicko! Sexy fingers at it again while old mate was in jp I accidently direct powered an earth and set the loom on fire. So a week later I had another mate wire it in for me. That was last fortnight I got it home which was an interesting event. Had no clutch fan and a 32 gtr rad ziptied in after the old fan decided to be really split and flail round as it span and put a big smilie face in my radiator. Waited til like 11 o clock at night to drive it down the freeway don't worry didn't cook it. I've had it home for the first time in about 7 months for the last week I've been tidying things up and trying to figure out why it won't play the game! Checked, afm, icv, tps, etc bit rich hunting, feels like vac leak have no vac leaks.. And that's where I'm upto!

Hey guys hope you don't mind first post being a question been asking on 31 club but haven't had a lot of replies. I've recently installed a series 1 25 into my 31. 109,000 kms on engine Redtop J pipe (no bov) 2.5 fmic way to big. standard dump, de-cat and 3" blast pipes. GFB boost controller set at 8 psi Bosch 040 pump As you can see it's stock. I have checked all the vacuum lines and swapped the j pipe because I thought the spring in the bov was gone and leaking. I've checked all silicone joiners. I have a boost gauge hooked up in the engine bay to help with diagnostics, no boost spiking or drop so I'd have to say it doesn't have a vacuum leak. I've changed the afm out with a couple others took a lot of the missing away but not completely. I've tried screwing the icv all the way in as well as unplugging it to see if that was the issue. I've tried adjusting the tps and put it back to where it originally was. Now when you start it it'll idle for a few seconds at 500 then raise and settle to a thousand rpm. Between 1000 and 2000 rpm it has a slight hesitation, car will drop revs below idle when you back off the throttle. Anything over 2000rpm when you back off throttle if you don't blip it the car will completely stall. Even if you're doing 5 grand in 4th... I'm really stuck here and getting a little bit over everything if I'm honest I'd just look to put some km's on it. If anyone has any ideas please let me know anything else to add to the list to check, and a few tips on how to check it would be amazing.
