For some time I have had a spare ECU, which is marked “190” so, assuming that’s correct, I thought I might get around to fitting it!
I know that fitting verniers would be the logical addition but - for originality - I was going to use the factory 190 inlet pulley. However I don’t have one…I do, however have a new spare std. pulley so here’s the question:
Hopefully someone out there will know 
I put mine in the recycling bin or you could have had them. Rumour always was they are not great and verniers are worth fitting. I think it’s hit and miss and depends on the car. I have verniers set on the dyno.
I’ve got a picture from somewhere that is supposed to show a 190hp pulley (see below). I think it will be difficult to exactly drill that additional slot without a good pattern. I used verniers ordered from Turbosport on Ebay. They wokred fine for me.
Thanks for the replies.
winthattt - it’s a shame you binned them, but not to worry…
As I have the spec I guess I’ll have to work out where the third slot goes. With trackrod’s picture it shouldn’t be too difficult (famous last words!)
I have a standard one marked up from an original one. However, why don’t you buy the dowels to advance the pulleys, You can actually time both inlet and exhaust. The 190 pulley goes on the inlet only. There was only one. See DVA. Ok, you need gauges to time the cams up so, your plan A is a quick solution but, still not optimised.

It is time consuming I hear.
I need to do this on a my Elise too-VVC engine as I am wanting to time up the upgrade exhaust cam and time both sides.
I think I may well have a spare pulley - I will have a check.
That would be terrific
All sorted many thanks to SimonE! Now all I have to do is fit the pulley & ECU, then start chasing the extra horses…
