Hi guys
In many ways is simple thing
When you in future will be buying Syvecs S6PnP you should be OK with standard inputs/outputs what have Syvecs as standard.
Here is our example:
We are running right now out the inputs,we have currently fitted Oil Temperature,Oil Pressure,Fuel Pressure,ACT(Air charge Temperature),NOS control and LC(Launch Control) switch.
In total is 5 inputs,now we have 1 free input and one EGT(K-Type/Thermo),which we can use on the NOS bottle heater/FFS(Flat Foot Shifting),Fuel Level sensor etc...
If we are want to use all those functions we will need 4 extra inputs and this I/O expander allowing us to have all this plus extra we will get Bosch LSU amplifier(as standard Syvecs using only NTK sensors,which are in general expensive),GPS(great for datalogging on track days) and other functions which I post above.
All those sensors(oil pressure,oil temp etc) you can always datalog or if you want them to see as gauge you can go route of the JTi Toucan or Digital dash.Toucan with all sensors is good investment on the Syvecs/AlcaTek,everything is all in one and you don't need at least gauges for everything if you want to see
Second good thing to have those sensors fitted is your mapper can adjust them,for example if oil temperature is under 70C you are in have limited performance(Limp mode) or if your Fuel pressure drop under value which has set your mapper engine will cut(this happens to us on Brands Hatch,at the end Fuel Pressure sensor has been faulty and he cut the engine to protect the engine) or when is Oil pressure too low,engine will cut or will go to Limp mode etc.,
Broadly speaking is worth the money,many people will carry out the driving(on track days or on the fast road driving) too with very low oil pressure or low/very high Oil temperature,with this Limp mode you will be forced to take car on side road or on the track days to Pit and check if everything is OK,at the end can be just something like happens to us Fuel pressure sensor has been faulty,if its just faulty sensor is good day,rather have faulty sensor than broken engine
First investment is higher,but at the end you will need gauges to have for controlling all those functions,if you are comparing price for Defi gauges(One gauge usually cost around £100-£150,some more cost) and you will need at least 3(with fuel pressure 4) and if you want to see the your AFR(Lambda) this means you will need 5 gauge(but you will need with integrated Lambda amplifier/controller and cheapest cost around £120) plus you will need sensors etc and at the end will cost you lot less than Toucan and full sensor pack
Shame Toucan is only available for Syvecs and AlcaTek,but when we are speak with Tim,he working on the OBD version for cars which have OEM ECU
Hope this help guys and if you have any question please ask,I'm happy to answer to your questions
