Hi,
I’m about to start turboing my mk1 1.6 eunos and have read on the ME221 website that you can use one map for a high and low boost application,

using a 3 port boost control solenoid would I be able to run a switch in between the solenoid and input to the ecu so that the solenoid could be not used to manipulate boost pressure? And instead have the max boost determined by the internal waste-gate spring?

Any help would be appreciated

Why do it this way and not just wire a switch to a spare input on me221 and have the ECU control the boost limit?

EDIT: I think we are talking about the same thing but you may have misunderstood the instructions on ME's website.

You just wire a latching switch or similar back to the ECU and assign the map to that input on MEITE, it really is that simple.

That makes sense, do you know if you’d need two indentical maps with differing boost limits within meite?
or would you adjust the boost solenoid duty between the maps?

I actually am unsure on that bit, I was working with Alex Hickson on my car, he did most of the map changes for me and I did the wiring myself. I wired up a button to a digital pin on the board and grounded it elsewhere, he then made the map changes. Unfortunately I switched it off as I was working to eradicate some other issues and needed to see if that was the problem (it wasn't), I never bothered to switch it back on but when I do the settings don't come back and I can't remember how to make them work xD

the simplest high/low boost control involves a switch interrupt on the boost control solenoid circuit.

and that's what I've got.

ME221 will be able to control 2 maps with different boost OL duty and Boost target map.

Im thinking that this might require a different VE map (which Miete allows for) and might need a different ign adv.. (again miete allows for 2 separate maps)

Ive wired my boost control solenoid to the carbon can connector - that didnt require any changes in IOs in miete.

Map selection will require wiring up a switch between earth and a digital pin in in the ECU
