CJ Posted December 30, 2003 Share Posted December 30, 2003 A friend of mine lives in the USA and has offered to buy Blitz 850cc, side feed, hi impedence injectors and ship them to me as a gift. These will cost me $130 each plus shipping. I have also been offered a set of UK 550cc injectors that will require a resistor pack. These will cost me about £380. Whichever I choose, I will also be buying an SAFC unit to control the fuel / air. My question is, would it be overkill getting the 850cc or should i get them as insurance for any further mods in the future? Any advice greatly appreciated.

arnout Posted December 30, 2003 Share Posted December 30, 2003 compensating that much fuel you need something better than the AFC. The AFC controls the injector duty (indirectly by modifying the pressure signal) but freaks up the timing a lot (also by modifying the pressure signal). i wouldn't go any much higher than say 15% or so (550cc is fine).

Ian C Posted December 30, 2003 Share Posted December 30, 2003 Agreed. The AFC is great for 550s, no good for 850s - you'd need, in order of £s, a new blank ECU, an E-Manage, or some other ignition timing controller. AFC may not offer enough adjustment for 850s either, they are almost double the size and the AFC only trims to -50% so it's right on the limit. -Ian Link to comment Share on other sites More sharing options...
TLicense Posted December 30, 2003 Share Posted December 30, 2003 CJ, If you go for the 550's, I may well be interested in the 850's. Regards Link to comment Share on other sites More sharing options...

arnout Posted January 1, 2004 Share Posted January 1, 2004 Originally posted by Gaz Walker Arnout, any reasons why? If you add up the prices for all the piggy back computers you need to get a good tuning of your engine, you can easily buy the AEM ECU. Furthermore I've researched the AEM a lot and I'm able to program it myself now. I think AEM ECU will be the killer app. in this new year. Link to comment Share on other sites More sharing options...
Darren Posted January 1, 2004 Share Posted January 1, 2004 Originally posted by arnout yeps. and got it for sale also, went AEM. I thought Leon @ JPS mentioned he had tried to set up E manage on a customers Supra and it had been taken off. Due to it not doing the business on the Sup. But I may be wrong......But thats what I thought he said! Link to comment Share on other sites More sharing options...

Syed Shah Posted January 1, 2004 Share Posted January 1, 2004 An AEM would be best to control 850s. Might as well do it properly now that the AEM is available. Link to comment Share on other sites More sharing options...

CJ Posted January 2, 2004 Author Share Posted January 2, 2004 Whilst I appreciate all the replies, i am now even more confused than when I first started. This now opens the other can of worms labelled "E-manage or AEM?". I can feel a major use of the search button coming on. Link to comment Share on other sites More sharing options...
Syed Shah Posted January 2, 2004 Share Posted January 2, 2004 Simple: Hands down the AEM. The E-manage is just another piggy-back IMHO. Only the AEM gives you true flexability and control. Link to comment Share on other sites More sharing options...
Adam W Posted January 5, 2004 Share Posted January 5, 2004 Bit late here but I was able to run 680cc injectors (up from 440cc stock injectors) with an SAFC, had issues with the ignition timing though. I definitely wouldn't want to go any bigger than that, getting it to idle would be a pig. If you need larger injectors than that, going from piggybacks to a replacement ECU will make your life easier, not more difficult. Link to comment Share on other sites More sharing options...

Ian C Posted January 5, 2004 Share Posted January 5, 2004 And I'd say E-Manage I got one for £300 with all the gubbins, and the interface is excellent so mapping will be easy for someone who knows how to do it (Pete Betts is going to be my first port of call). I reckon under a grand for it installed and mapped and it controls fuelling and ignition timing and you don't have to worry about cold start mapping, idle up, aircon, PAS, lights, etc etc because the stock ECU still controls all that. Discussion Further discussion Bearing in mind that I was 100% for aftermarket ECUs before I entered into this discussion. Arnout's done more engine work than I probably ever will but I don't know what extra piggyback stuff he's on about, an E-Manage is the only piggyback unit required as far as I can tell. I hope it is, I've got one We shall see... -Ian Link to comment Share on other sites More sharing options...
Nic Posted January 5, 2004 Share Posted January 5, 2004 Ian good luck with the e-manage install, I'm sure you will be very pleased with the results. If you have any issues let me know and I'll try to get answers from the guys who mapped mine. cheers Link to comment Share on other sites More sharing options...
Guest Terry S Posted January 5, 2004 Share Posted January 5, 2004 Hi Nic, any chance of e-mailing Ian your map, as it's always good to have for reference. Link to comment Share on other sites More sharing options...
Ian C Posted January 5, 2004 Share Posted January 5, 2004 Bloody good idea Terry - Nic, that would be fantastic if you could, PM me for an email address Thanks for your offer of help as well, very appreciated -Ian Link to comment Share on other sites More sharing options...
Nic Posted January 5, 2004 Share Posted January 5, 2004 I presume by the 'map' you mean a visual of the setting mine is set to I'll see what I can get and send over in the next couple of days. Link to comment Share on other sites More sharing options...

Nic, there is probably a calibration file for the e-manage if you plug in the lap top. The e-manage should have the ability to store different maps ( cal files) for diffent fuels or set ups. If you sent Ian over the basic cal file as an attachement he should be able to open it with his software, or load it directly into the e-manage.
