Noz Posted July 24, 2013 Share Posted July 24, 2013 I'm on the hunt for a new ecu. So for this reason I'm looking into whats on the market, its functions and what's important when selecting an ECU. I've had a look, and the syvecs processor speed seems to be one of its flagship features. Being able to control and react quickly. Apart from the number of inputs, outputs or listed features have any opinions on the differences through actual use. My main interest with a new ECU is datalogging and fine adjustments with heat removal and fine tuning. I'm not looking for major power, a new ECU will allow me to tweak things and see an improvement. My engine is my R&D project and I need to take the electronics to the next level. Please only educated responses. "Syvecs is the best" gets a bit boring.

Luxluc Posted July 24, 2013 Share Posted July 24, 2013 Isn't the S6 intended for Supra's and the S8 for GTR's?? Quote Link to comment Share on other sites More sharing options...
Noz Posted July 24, 2013 Author Share Posted July 24, 2013 The only information I could find online was the number of inputs? Quote Link to comment Share on other sites More sharing options...
Justin Bieber Posted July 24, 2013 Share Posted July 24, 2013 I'd imagine your best bet would be to give Ryan or someone from Syvecs a call and discuss your requirements Quote Link to comment Share on other sites More sharing options...
Noz Posted July 24, 2013 Author Share Posted July 24, 2013 I'd imagine your best bet would be to give Ryan or someone from Syvecs a call and discuss your requirements Until I know what capabilities of different ECU's are I won't know which one I'd prefer Plus there isn't a lot of discussion about control of the ECU's from a users point of view on the forum.

Luxluc Posted July 24, 2013 Share Posted July 24, 2013 As far as I know, the S6 will control everything for the Supra .. from boost, TRC up to the surveillance of the different temps and pressures (if you fit all the necessary sensors). I will fit a Toucan next months to have everything displayed on one monitor and to allow me to remove all those gauges. Quote Link to comment Share on other sites More sharing options...

The S6 is more of an entry level ECU and the S8 is more feature-packed. S6 has a single wideband input, S8 has 2. Same for thermocouple inputs. S6 has no igniter outputs built in, S8 has 8. S6 has a single CAN interface, S8 has 2. S8 has more inputs, so can accept more sensors and still use DBW, etc. And from memory, the S8 gets the new strategies first, which are then trickled down to the S6.

David P Posted July 24, 2013 Share Posted July 24, 2013 The S8's £2.5k price tag is more than your car's worth. A second hand AEM series 1 would manage your N/A-T for 2k less. Quote Link to comment Share on other sites More sharing options...

Very good point, or if you do really want to push the boat out the highest I would go would be S6 Quote Link to comment Share on other sites More sharing options...
Wez Posted July 24, 2013 Share Posted July 24, 2013 Either S6 or S8 will do what you want, depends on your budget, most Supra run the S6GP, TLicense went for an S8 on his twin Blitz build as he wanted more IO. For more info have you tried the Syvecs forum http://www.syvecs.co.uk/forum/ Quote Link to comment Share on other sites More sharing options...
Littler Posted July 24, 2013 Share Posted July 24, 2013 Is the syvecs I/O expander an option for the S6 or is that only for the S8? Quote Link to comment Share on other sites More sharing options...
johnny g Posted July 24, 2013 Share Posted July 24, 2013 Is the syvecs I/O expander an option for the S6 or is that only for the S8? It's for the S6 IIRC, but the strategies still go to the S8 first Quote Link to comment Share on other sites More sharing options...
Noz Posted July 24, 2013 Author Share Posted July 24, 2013 (edited) The S6 is more of an entry level ECU and the S8 is more feature-packed. S6 has a single wideband input, S8 has 2. Same for thermocouple inputs. So two AFR and two EGT? This would be I assume to get better accuracy. This wouldn't be much use on a single scroll manifold on a six cylinder I assume? S6 has no igniter outputs built in, S8 has 8. How does this make a better ECU, sorry for being dumb S6 has a single CAN interface, S8 has 2. This would be for dash setups etc? S8 has more inputs, so can accept more sensors and still use DBW, etc. The S8's £2.5k price tag is more than your car's worth. A second hand AEM series 1 would manage your N/A-T for 2k less. I don't want to just manage me NA-t though mate. I want to learn about how to get the full potential out of an engine. Each sensor input must have an optimised value for the engine, therefore I'd like to use my engine as a tool to learn. I feel I can learn more with a premium newer technology ECU, whatever the make.

Noz Posted July 24, 2013 Author Share Posted July 24, 2013 Looking at the price of syvecs, vs other ECU's, it seems the main cost difference is the sensors. Wouldn't other ECU's perform better if they also used better sensors? Obviously the answer is yes. I think maybe comparing ECU's would give me a better idea of which functions are missing on other models, and which I don't think I'd use.

ashbuster Posted July 24, 2013 Share Posted July 24, 2013 1.5k for the ecu alone i think then 500 for the screen and the rest is sensors and mapping Quote Link to comment Share on other sites More sharing options...
Wez Posted July 24, 2013 Share Posted July 24, 2013 Looking at the price of syvecs, vs other ECU's, it seems the main cost difference is the sensors. Sensors are not rocket science, as long as you have the calibration info you can configure them for use on most aftermarket ECUs, the difference in price is mainly down to accuracy, response time and packaging, ie fitment and weight Quote Link to comment Share on other sites More sharing options...
Wez Posted July 24, 2013 Share Posted July 24, 2013 Wouldn't other ECU's perform better if they also used better sensors? Obviously the answer is yes. I disagree, all the sensor is doing is providing information, its the ECUs code/logic/strategies that determine how best to use that information Quote Link to comment Share on other sites More sharing options...
