I'm gonna leave it in for now at least

been at work all day so not got a lot done but I have finished the fuel rails and run the Z up and it's looking good.

The evap line should be the one nearest the back

Excellent I look forward to it

Oh and don't think you can get away with picking holes in my spelling Mr keyboard warrior there's been a lack of grease monkey action from you lately are your hands getting soft like a lady's Hmmmm are they ?

I was just checking to see if you actually read it

another one of those small issues came up that turned into an all day job, the fuel rails were wet where I welded them so i took them off and ground them back to try again turns out the weld is porous I'm guessing the rails were brazed originally even though I ground them back to bare metal I had the exact same problem again not sure if it's impurities in the metal or what but I can't be arsed to do it again. So plan b or c I can't remember anyway the fuel rails that were supplied by OBX have been on a major diet with the aid of my milling machine and a finger sander and now fit just. I'll post up a couple of pictures when I get a chance also I've started on the air filters

yea that "kit that's ready to go " bit is a bit misleading but if anyone feels the urge to try it it's not too bad especially if you go over to a cable throttle pedal setup then the only other problems are the passenger side rocker cover the breather pipes and the fuel rails other than that it's feasible with a set of drills and taps and a lot of patience

yes it started first turn of the key about an hour ago then the heavens opened up so I'm sitting here in my pants looking like a drowned rat but smiling like this The suppliers /manufacturers were useless with the issues apparently I don't know what I'm talking about I machined a pulley to go onto the throttle servo so it's all cable operated for now anyway also had to blank another one of the breathers on the rocker cover I cut and welded the standard steel fuel rails to fit and strangely they came out similar to the Jenvey ones so Jenvey don't know what they're talking about either and completely re-did the fuel system and vacuum setup much neater and there you go just lots of tinkering now to make it run right oh and sort out air filters

did you upload the parameters file to the parameters tab or to the aps tt map ? there is only one set of parameters on the utec and it is applied to all maps on the ecu

maybe you saw it in the documentation they never updated it when they changed the firmware also you need the correct parameters map to go with the rest

pretty sure 2.8 was the last and latest version so you can't set the injector size also bearing in mind I haven't played with one of these for a while I think you have to either alter the 0% load column which will adjust the factory ecu fuelling or set the open loop thresholds so that it doesn't revert back to the factory ecu other wise the factory ecu will be running your larger injectors with it's standard timing

if you can see the injector size under constants you must have the old firmware but just beware you may also come across the opposite problem of running an new map on old firmware but in that case the mixture will be lean

there is an issue with some maps for the utec ,because when they changed the firmware they removed the setting for the injector size so if you have a map written for the early firmware and they used this setting it is ignored by later firmware and your fuelling will be out you can pretty much assume that any non oem injectors will be bigger so this will result in a rich mixture in this case if you change the ECU consider the link G4+ plugin ecu I went from a UTEC to this and I love it totally differant league

try this

no they would have to be huge anyway it doesn't matter the modified ones are nearly ready to go, and the chinese are usually so good at copying other peoples work

It's highly unlikely that they will fix anything but if I document the problems and fixes for them here you can at least make an informed decision as to weather you want to give it a try none of the issues are major or insummountable some drilling and tapping and a tiny bit of welding for the fuel rails

So the next problem (I'm sure it won't be the last) is the fuel rails' I dropped some injectors in tonight and thought to myself that looks a little tight it doesn't matter which way around you put the injectors or the supplied fuel rails they either sit on top of the injector connector for the other bank or just push the injector over at an angle unless the injectors were about an inch longer these fuel rails would never fit luckily I have a spare set of standard fuel rails that I've started modifying to fit even though I expected a certain amount of problems that doesn't mean it's acceptable and I have got onto the supplier about the various issues especially as they suggest that this is virtually a bolt on kit

anyone guessing the montego should be banned from the forum for knowing such a hideous piece of crap so intimatley

well her is the link to the obx install if you're interested

you mean attempt no.3 the first one using bike throttle bodies worked really well I only started again because I was being anal

A lot of my day has been spent doing things obx should have done properly tapping holes through that were only partially done countersinking some holes properly etc mostly minor stuff but it still had to be done and still took time also you can't bolt it all together on the bench and then fit it, everything has to be built on the engine due to clearancesbeing so thight. so here is my days progress still plenty to do my aim is to get it started next weekend, maybe possibly

So out with the old So now I can see what it fits like good so far that is untill you fit a throttle body and velocity stack anyway there is no picture of this yet as not a single one fitted. with a standard 350Z rocker cover the filler would be in the way luckily I've already changed mine as I already had this problem with first ITB setup I had this one is from an Elgrande I believe, despite that I still had to modify the cap I made, cut off and blank the front breather pipes and all of the brackets the injector loom fixes to and clearance is still tight the other thing I've had to do is reroute some cables, nothing too drastic (yet) I've also drilled and tapped the manifolds for the vaccume takeoff neither the OBX or jenvey come with this pre-drilled an tapped Hopefully I will get a bit more done tomorrow

For many reasons already discussed in my DIY individual throttle body thread the project has been abandoned and as per the title I'm installing OBX individual Throttle bodies which arrived wednesday 3 days from america not bad These have had a lot of bad press but strangley I've not come across anyone who has actually fitted them it's all hearsay. Jenvey are understandably upset as they appear to be a direct copy of their setup so I can see their point after unpacking them and having a good look some of the criticism is definatley fair the quality of the castings and machining of them is not up to jenvey standards and there are no instructions whatsoever not that I would have read them I'm a man god damn it. The throttle bodies look good and the parts supplied quite comprehensive if I paid jenvey money for them they would go back but I didn't I paid a third of that
