Sheefa Posted December 28, 2006 Share Posted December 28, 2006 Hi guys, Hoping you can all provide some advice on a fuelling upgrade I'll be looking at in late February. Currently have a J-Spec Supra TT with standard 440 injectors but uprated Walbro fuel pump. I'm running on hybrids at the moment and not boosting above 1bar at all, especially in the winter. Fully decatted, FMIc etc, full spec below in Sig. I do however worry about the fuelling, even through my AFRs appear fine and Chris Wilson has confirmed. I'd just like to run the car a little more safely and perhaps have a ready setup for a small single sometime next year. I've been looking at an EManage Ultimate, but would appreciate advice on other parts, injectors etc needed. Excluding the EManage, my budget is about £1,000 TOPS. I have NO experience of mapping etc so need to pay a visit to a decent mapper Thanks, Greg Quote Link to comment Share on other sites More sharing options...
Alex Posted December 28, 2006 Share Posted December 28, 2006 Well mapping an EMU is easy enough - bring the car to Norwich But does your 1k inc paying the mapper? Injectors new cost about £80each (for good ones). Drop in fit for the stock rail is a must for your budget...so go for PE650's. Nic will supply these along with the EMU and all the harnesses etc that you *need*. You'll want a fields harness too, to wire in the EMU. So EMU + PE650's + Field Harness (wiring loom extension) + mapper. The Walbro pump will surfice for the Hybrids and upto about 600Hp.

Sheefa Posted December 28, 2006 Author Share Posted December 28, 2006 Thanks Alex. I'm awaiting delivery of the EManage and it does come with the harness already and the injector adaptor too. It has no Pressure Regulator however, I'm told that's needed to run more than 18psi (how much in terms of 1.2 etc boost is that???!) so may need to source one too. Are the PE650's drop straight in then? No resistor pack needed? How much is mapping normally then and who's based in Norwich mate - Turbofit?

AshBhp Posted December 28, 2006 Share Posted December 28, 2006 What power/boost can the Stage 3 Hybrid Turbos handle? Quote Link to comment Share on other sites More sharing options...
Sheefa Posted December 28, 2006 Author Share Posted December 28, 2006 No ideas Ashbhp. But I don't want to go ANY higher than 500BHP that's for sure! Quote Link to comment Share on other sites More sharing options...

I think you mean the EMU's Manifold Pressure Sensor. Yes you will need one of these to map over 1bar (accurately). Are the PE650's drop straight in then? No resistor pack needed? Yes they are. How much is mapping normally then and who's based in Norwich mate - Turbofit? lol Yeah cause they can map an EMU...not. No IanC is the man for EMU's.

Chris Wilson Posted December 28, 2006 Share Posted December 28, 2006 Leave it alone until you go single, and then buy a proper ecu. That's my advice! Quote Link to comment Share on other sites More sharing options...
Sheefa Posted December 28, 2006 Author Share Posted December 28, 2006 Yes but I doubt I'll go single Chris. I'd prefer to squeeze the juice out of the hybrids with a good fuelling setup first mate. I'll have to sell the car in mid 2008 probably so won't be investing loads of money into her. Anyway, this is more work for you as I was going to give you a shout about injector supply and install, maybe twin walbros etc! Greg Quote Link to comment Share on other sites More sharing options...
Alex Posted December 28, 2006 Share Posted December 28, 2006 You will not need twin walbro's 100% guarenteed (ASSUMING your original one is the GSS341/342 that should have been fitted) Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 28, 2006 Share Posted December 28, 2006 The fuelling as it is will be fine for all the sequentails can give, much as I'd like to take some more dosh of you. The last thing you need is a signal fudger, the fuelling was good, I checked it on my Motec readout. If you REALLY want to spned just buy it a new single Walbro, for peace of mind, and check it has GOOD plugs in it. You don't need bigger injectors, any add on ecu, or any of that sort of stuff for hybrids. Quote Link to comment Share on other sites More sharing options...
Sheefa Posted December 28, 2006 Author Share Posted December 28, 2006 OK thanks Chris. I think you replaced the plugs in August during its service anyway IIRC. Maybe a new fuel pump is the best bet now just in case, but if the fuelling is good like you say, no point on spending the cash just yet. Cheers Chris. Perhaps I should invest the dough into a nice suspension setup instead Thank you too Alex Quote Link to comment Share on other sites More sharing options...
Alex Posted December 28, 2006 Share Posted December 28, 2006 I disagree with Chris here. Hybrids are "best" at 1.4bar and you're only able to 1bar safely with the fueling you have. To enable you to run 1.4bar you should increase injector size and use the EMU to control them. However I think you can make the fueling corrections even easier by using PE 550cc drop in high impedence injectors (model=SH550A). The less the signal fudger does the better. And there are other benefits to the EMU, it's got a built in SLD, FCD and Rev Limit defeater...you can have all this + timing and fueling control in one box and sell the other ones. But anyway, it's up to you. I know Chris would prefer you to just whack a Motec in it, but then CW hasn't been out in IanC's car yet Quote Link to comment Share on other sites More sharing options...
Sheefa Posted December 28, 2006 Author Share Posted December 28, 2006 Ah that's a good point Alex. So I could recoupt some of my spent cash on the TRD FCD and Limiter etc - nice Still confused as to what to do now. As mentioned, I haven't ever gone above 1 Bar of boost yet so I won't be reaching dangerous levels, but would like to play it safe. Who's the best person/trader to see for these injectors Alex? Thanks, Greg Quote Link to comment Share on other sites More sharing options...
Kranz Posted December 28, 2006 Share Posted December 28, 2006 Greg, I'm going hybrid, decat, fmic, walbro etc the same as you. I'm doin it the least expensive route possile though, using S/H parts where possible. I've bought a set of Uk 550's (£90 inc post) and will be using a SAFC 2 (£100) to fiddle it (if Gruggs ever gets it out of the car LOL). If it needs any more I'll stick an aeromotive on there. I'll be investing in a wideband readout too, so I can keep an eye on the fuelling. As Alex says, 1.4 bar (20 psi) shouldn't be a problem for decent St3 hybrids.

Thanks, Greg Nic. I forgot you'll need a WB02 sensor too if you haven't got one already...it needs to be plumbed into the 2nd cat pipe.

Sheefa Posted December 28, 2006 Author Share Posted December 28, 2006 Thanks Steve. Yes mate, got pretty much everything sorted except the injectors and EMU/Fuel control really. I've heard mixed reports about the SAFC-II which is why I went EManage Ultimate but I've heard they're perfect for 550's. Not sure whether I go drop in ones at that size or up them to 650's to be safe. Have AEM AFR gauge, FMIC, Walbro etc fitted already in good condition so not that much to do. Going to swap the tranny cooler you sent me over too! Let me know about payment for that as per my PM buddy! Did you have the 550's cleaned and flow tested mate? Alex - any ideas how much Ian C would charge to fit and map the EMU? I know Thor Racing do it for £400 including the discount for Xmas.

Sheefa Posted December 28, 2006 Author Share Posted December 28, 2006 Nic. I forgot you'll need a WB02 sensor too if you haven't got one already...it needs to be plumbed into the 2nd cat pipe. That should of been fitted with the install of my AEM UEGO AFR gauge right Alex? Quote Link to comment Share on other sites More sharing options...
Alex Posted December 28, 2006 Share Posted December 28, 2006 Ian's about £300 for a full mapping session - but you can have a best guess map for £150. Yeah it should have been installed with the AFR gauge Quote Link to comment Share on other sites More sharing options...
Nic Posted December 28, 2006 Share Posted December 28, 2006 Nic. I forgot you'll need a WB02 sensor too if you haven't got one already...it needs to be plumbed into the 2nd cat pipe. Thanks Alex Greg is you want any details/prices for any parts give me a shout, I can do good deals on all the parts you need. Quote Link to comment Share on other sites More sharing options...
Sheefa Posted December 28, 2006 Author Share Posted December 28, 2006 Thanks again Alex. Nic, thanks mate. I think I'll look at getting some PE650s that drop straight in buddy. Please PM me with details of injectors and accompanied prices that will fit STRAIGHT in to my stock J-spec rail without any modification, resistor packs etc mate I will also be needing a pressure sensor for the EMU too, and maybe something else that I might of missed off the list, don't know what though! Thanks Nic. Greg Quote Link to comment Share on other sites More sharing options...
Alex Posted December 28, 2006 Share Posted December 28, 2006 Nic quote him on the 550's too 550's are good for 550BHP (roughly) and the smaller your injectors the better the control Quote Link to comment Share on other sites More sharing options...
Jake Posted December 28, 2006 Share Posted December 28, 2006 You'll want a fields harness too, to wire in the EMU. it does come with the harness already and the injector adaptor too. Just to point out that the EMU harness and a Fields harness are different things. Ideally you'll want a Fields harness as well as the EMU one (well, whoever installs it will really prefer you to have one) Quote Link to comment Share on other sites More sharing options...
