crock Posted October 5, 2015 Share Posted October 5, 2015 I'm in the middle of piecing together my parts for a single turbo build to undertake over winter, Its done on a budget which i understand people regard as a waste of time on here involving a supra but i feel it can quite easily be done to achieve the goals I’m after (550+bhp) The questions I’m wondering is involving the last couple of bits, ecu and injectors Ecu: i know the answer to this is going to be syvecs, but i have been quote from a local dealer £3300 supplied fitted and mapped, its the ecu i think i like would like to run, but i'm not sure if this is because it seems to be the only answer given on the forum, I see the skyline community are having good results for the Link g4+ ecu has anyone run one of these successfully in the uk? Injectors: after hours of research it seems the stock fuel lines (including fuel pulsation damper) and fuel rail and FPR is able to support 600bhp with drop in's. I'm looking at sard 800cc or 850cc injectors, these seem to receive mixed results should i be looking elsewhere or will these be okay for my power goals? cheers in advance Crock Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted October 5, 2015 Share Posted October 5, 2015 ECU's, the best way top do it is to find a mapper you trust and listen to what they recommend. Syvecs is one of the best out there, no question, thats why so many people recommend them. Yes they're expensive but you get what you pay for in management, and you should pay up because you'll get better results. Why people spend lots of money on a single set up then run it on an eManage blue or stock fuelling is beyond me. Link are a well established brand in the UK. A few people also go on about Haltec. Injectors, rule of thumb is 1CC of injector capacity per hp so 800s will give you a nice bit of duty cycle headroom Quote Link to comment Share on other sites More sharing options...
absz Posted October 5, 2015 Share Posted October 5, 2015 I run a Aem v1 Ecu mapped at 600bhp running 880cc sard injectors and does the job with no issues, Supra engine management is old technology and your goal can be achieved using a ecu like G4/haltech etc . Syvecs gives you more control on transmission /traction control it has the ability to monitor oil/fuel pressures etc and also can change injector duty if fuel pressure drops so it controls the engine more safely,but you can achieve this my monitoring your gauges and right foot.newer cars with driveby wire and canbus then Syvecs is one of the best Ecu's to have Injector wise ANSU will be my choice which are bosch injectors rebranded they have less lag time which makes them easier to control and map, a good mapper will be able to map any ecu like ryanG did before becoming a director of syvecs Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted October 5, 2015 Share Posted October 5, 2015 AEM are capable, but they have a known history of failure. You have a few options really, Apexi power FC or HKS Fcon are available second hand for good money, and there are a few mappers out there for each type. Motec, Link or Syvecs are among the top, and most (including me) would point you in the direction of Syvecs, mainly because they have a proven track record and are the most experienced when it comes to tuning Supras in the UK. One you factor in the saftey strategies, multiple maps and traction control, the Syvecs is really the optimal solution. Quote Link to comment Share on other sites More sharing options...
SaqTRD Posted October 6, 2015 Share Posted October 6, 2015 Isn't the AEM failures down to mapping? Or are you saying the unit themselves actually fail? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted October 6, 2015 Share Posted October 6, 2015 The units fail. I have an 800 quid paperweight sat on my unit shelving. Its a known problem and AEM will repair and upgrade them to Ver 2. For 600 quid. Plus shipping and taxes. Quote Link to comment Share on other sites More sharing options...

One you factor in the saftey strategies, multiple maps and traction control, the Syvecs is really the optimal solution. in regards to being proven with supra's it seems anyone who has ran a syvecs used ryan to map the car, as i understand he has now left the country to go do saudi? i know grasp the conecpt of the build and reliability comes down to the map alot of the time, i'm just curious why everyone goes syvecs? was it the support ryan gave? if there was another forum member who was a mapper using the likes of link or motec would people use that system? in regards to the fueling and injectors would it seem then to be a better idea to use a aftermarket fuel rail top feed injectors and fpr? i just been researching off previous threads and it seemed the stock fuel system with uprated pump and injectors would be fine for my needs? i have a walbro 450lph to fit and then add the sard 800ccs (or other side feeds if available?) and that would of been the answer to my fueling there is no real rush to my build if it takes a bit longer that so be it, the cars coming off the road shortly for winter anyway, i've always like the idea of keep it simple, so if the aftermarket parts were not needed then is there any real need to fit them?

Do you know what part fails or does it not power up, Just Curious as I've had no issues over 5 years now Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted October 6, 2015 Share Posted October 6, 2015 Do you know what part fails or does it not power up, Just Curious as I've had no issues over 5 years now In my case the interface between the harness plug and the board, it wouldn't communicate. Cant speak for the rest Im afraid. Mine is an AEM EMS V1 Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 7, 2015 Share Posted October 7, 2015 I like thw Link ECU's and if you are on a budget they should be fine. I find the Link software intuitive too, although I am not a proper mapper I am happy to tweak things. The very very best support and widest number of professional mappers comes when you buy a Motec though. Quote Link to comment Share on other sites More sharing options...
bignum Posted October 7, 2015 Share Posted October 7, 2015 Its the injector drivers which are known to fail on the older aems, if it occurs whilst on full chat its bye bye engine, I switched to syvecs, runs the engine so much smoother than the aem. also I was interested in the safety that syvecs gives.

Chris Wilson Posted October 7, 2015 Share Posted October 7, 2015 I would be interested in getting my hands on an AEM with a failed injector driver issue, to see if I could repair it at the component level. I can now do surface mount component work and am curious to see what devices they used, and what they replace them with. Quote Link to comment Share on other sites More sharing options...

I think you to say you like something is quite a high praise, i did hope you would have some in put in regards to link, as you are a skyline man and they seem quite well praised with the skyline owners, I have a link mapper i could use around 10 miles away who a friend is using to map his ground up r34 build or a syvecs mapper 40-50 mile away, I havent looked at motec in all honesty Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 7, 2015 Share Posted October 7, 2015 I have had at least two MKIV's in on Link ECU's, one was sold on here with a cracked block, an auto TT converted to a medium sized single, the other a manual six speed TT converted to a small single. Both started, drove and worked fine. MOTEC is expensive, but support is the best in the business, and probably more pro mappers worldwide are familiar with it than anything else. They have a support forum with webinars and all sorts, well worth a look as a lot of info is generic. http://www.motec.com.au If my Motec plays up (it never has) or I need support I can get it 24 hours a day, either their UK headquarters, their USA headquarters, or their Australian headquarters, by phone, e-mail or web forum. To me that means a great deal. They must have at least 30 factory recommended mappers in the UK alone. Quote Link to comment Share on other sites More sharing options...
