Hi guys,
Trying to activate the solenoids with MSS three days now but nothing.
The problem is that I checked the wires with a led light and it cuts the power at the rpm I have set it. But the solenoids do not activate!!! I wired them back to stock ecu and they work just fine. I have read all related threads and I have done the most combinations with settings.
Does anyone know what is SP1-SP2 and S1-S2-S3-S4?
Thanks in advance,
Bill
Just, to check the most obvious thing first: you wired 12V positive to each solenoid and the other wires from the MSS (green and yellow) are feeding ground to the solenoids, right?
Give us a summary of your wiring layout for the MSS, maybe something will pop up out of that.
And, to confirm, you are following Steve's setup instructions at this link?
Bill,
It is not a wiring problem. I have stock 20ve ecu and followed the wiring described at www.sr20ve.co.uk
Everything looks fine. RPM, voltage(TPS) and km/h showing right. I know that MSS must give ground to activate the solenoids. As I wrote above I have checked the wires with a led light. It stays on when engine starts and goes off at 4800 rpm, where I have set the MSS to activate the solenoids. Although solenoids do not activate.
I would be surprised if both solenoids are faulty. My questions to Bill in Athens would be:
1) What wiring loom are you using to connect the solenoids to the ECU? Are you using the complete connectors and actual wires from the SR20VE loom?
2) If you have used the FUSE block in the GREDDY MSS kit then you have NOT used a relay. If you have abandoned the Fuse block and fitted a relay then whay not trial a direct connection (bypassing the relay).
@ garyd:
It is not solenoids problem. When I wire them back to ecu (stock ve) they work fine.
@ Paul:
Yes, I have the stock ve wiring loom.
I take power for MSS from car's fuse box (two 10A fuses). The green and yellow wires go direct to solenoid wires.
@ Steve:
Yeah, I know.
Can anyone answer the questions I asked in first post? Those greddy guys have to understand that japanese is not the most common language all over the world. Things would be very simple if they had a f@@@ing english manual.
Bill,
From you reply I guess you have these wire colours:
Yellow wire - Inlet Solenoid, Orange Black wire (ECU pin 102)
Green wire - Exhaust Solenoid, Green Red wire (ECU pin 106)
You've connected the pair of +12ve supply wires from the solenoids to a motor on power feed.
You mention a pair of fuses for the MSS, I'm assuming an in line fusible link on both the +ve & -ve feeds into the MSS.
The interconnect between the solenoid wires, you need a decent spade and receptacle or solder joint to transmit sufficient current for the solenoids.
Setting up the MSS, I think you may have the triggers reversed in the programming. Try to return the MSS to default settings then re-read my instructions on the website.
If it works w/ the ecu, what are the settings for each "channel"? If you have SP1 turn it on at something like 3500 (just to check them) and off at 3700, how does it act? Do you have one of the settings set at 0?
Ok guys,
Two more wasted days. I am really upset with this thing called MSS.
The news is that everytime I make a change and then go back to real time screen it has new settings.
I will make it as clear as I can:
I set it to:
Rpm1- 4800 on, 4790 off
Rpm2- 4900 on, 4890 off
Volt1- 0 on, 0 off
Volt2- 0 on, 0 off
Km/h1- 0 on, 0 off
Km/h2- 0 on, 0 off
It doesn't work and then when I go to setup screen and set something (let's say the little dash on Tp) and then come back to real time screen and hit the mode I have settings like on and off at 90Celcious. WTF!!! I set temperature to zero and then I have something else!
Something else I have noticed is when I set both Pr and Bo little dash on top or bottom
it beeps continously.
Still noone answered my first questions : What is SP1 and SP2 and what the use of them? What is S1 that has the littlle dash on top and when I rotate the set button the little dash stays always on top and it becomes S2, S3 or S4?
Hi Bill,
I'm sorry that you're having trouble. It can get confusing once you've lost the original positions. I believe that the settings you are asking about are:
Channel 1
SP1 sensor postion one
SP2 sensor postion two
An example of this would be:
Solenoid 1
Switch on earth as revs pass 5,400 rising (SP1)
Switch off earth as revs pass 5,400 falling (SP2)
For the programming to work you have to set the chosen measurement parameter (revs & TPS). The Nissan motor (S2) & The speed sensor - Pulse 2 (P2)
remember that there are manyprogramming
button pressing features: single click, button hold, dial twist and click etc.
Your settings are not recommended, make the rpm values identical, if you have the TPS setting off then this will act as a conditional rule and keep your solenoids off!
Whay not set TPS to on at 3.00Volt rising and off at 3.00Volt falling.

Glad you got it fixed. The MSS is a generic device, it can be used for all kinds of situations, eg a electrically actived spoiler could be raised at a certain miles/hour. These features are for other applications that give you diversity in the MSS product. You simply have to ignore them for the solenoid applciation.
Cheers Paul
