My car has been through more than one IRMC box. To be honest when it wasn't working I couldn't tell any difference and it passed the emissions no problem. Of course now having an EML light on will fail the MOT. A lot of people say the ST doesn't produce power. My car is stock apart from K&N in the stock induction the IRMC box was actually playing and it was running Supermarket fuel. It was on Rick Savage's dyno a few years back as a club meeting. It recorded 169.1 so I refute the doesn't produce power claim.
169.1 is a near perfect result yours must be in great condition! People compare the ST170 with lots of other cars and for sure some complain about the power. They were designed with that power and that’s the character of the car - a b road car you’ve gotta work hard and be busy driving to get the most out of it. That’s the fun! The power is modest by todays standards and gearing is not set up for fast 0-60 sprints. They’re motors you’ve gotta actually drive at higher RPM which is great 😄 They are super sensitive to servicing especially after 20 odd years. People that drive them and report they feel particularly ‘flat’ have likely got some issue somewhere but again it depends what it’s being compared with
Several different imrc issues relate to differing failed components .... all the specs for components in the imrc are available on SVT and ST220 forums you don't need to guess ....
Also, for future, hopefully you never have to do this again but an alternative to a solder sucker is just a bare copper braid. Sometimes that works nice as well. Great video.
Oh nice I’ll give that a go. I could use all the advice I can get when it comes to soldering! Hopefully I won’t be repairing the same IMRC again but you never know ha!
Add some heat sink putty to your arsenal. So far an amazing series on you ST rebuild!
Will do. Thanks for watching! 👍

This video should be huge. Mine needs this fix.

@@st170restoration ha I hear you there. I hate doing stuff twice!
Nice vid mate. If you desolder something add the new solder first. It will melt old solder better.
Nice one will do! Thanks for the tip 👍
I have a replacement one to fit. Just never get around to it
Great to have a spare! They come off surprisingly easily
what is the part number for the Mystery Chip?
Hi the full listing for it reads as follows - 1N5404 3A 400V Rectifier Diode. As of yet still untested so watch this space! 👍
