ST170 IMRC fix

[@AWESOMEAzA12]

Absolute legend for this mate! looking forward to getting this sorted, and getting her through her MOT.

[@ArranShort]

Super helpful video! I've just pulled my IMRC off and it had dry joints on the connector and transistor and not even a screw holding it on!

[@jpst170]

Glad it helped you buddy 🤓👍

[@kylejulies1692]

All these st170 seems to have the same dam issues. My spring that connects to the cable came lose and I just mixed a little pratley steel and it never gave me a issue again

[@ZEV79]

Thank you for your video. I.learned something new. Merci 🇨🇭🇨🇮

Yesss mate, good job 👊🏼👌🏼

Nice job mate good video

cheers buddy

[@dasedas]

Thanks mate. One question, there is not any seal on the body of imrc? U put back the cover without anything.

[@jaibroca9433]

Please how did you know it was the transistor´s fault? Thanks from Spain!

[@Cherokee801]

Very good video. Thank you.

What battery will you say worth for st170 is it necessary to by bosch

Sweet video!

Thanks for the video it helped a lot. I needed to replace trazistor, mine was MJF6388G . I use a tranzisor TIP102 as direct replacement for 2N6045G. It works on start, I am not sure if it works at 5000rpm.

[@djiricka]

So error code occurred again.

[@Antrollor]

Thanks a lot !! I fixed it thanks to your help. Finaly, after a lot of tests, it was an electrical harness problem. But with your video, i was able to do it. Best regards !! My St 170 is young again. Thnaks !!! (^_^) !!

Top job fella 👏

[@jpst170]

thank you buddy 🤓👍

[@eupatt]

Hi Does the spring is supposed to do a full turn ? I opened my IMRC and found a lot of aluminum dust : the long leg of the spring has « eaten » the side of tbe casing… So when I turn on the car the little just keep turning and never lock

[@adamsst170bluesmurf3]

Nice video mate common fault i think a lot of people will try to have a go themsleves now 😉

[@FOCUS.GSXR600]

Where can I get the resistor from please

[@mfamily3173]

Hi mate what does bt326 code for and also u1262 and what are the symptoms can you help explain please I’m lost

[@plumbc007]

The tip 121 transtior is actually need to cool down hence the thermal paste not for better connectivity

[@powerpower1797]

Good video.

[@LifesAbe-ach]

What were the symptoms on yours , I have one that pulls then after a few seconds releases the cable .

[@jpst170]

poor fuel consumption and a loss of top end power

[@benrampling812]

I have the same mate, have you found out any more about it? Only other thing I have found (assuming it's electrical outside of the IMRC unit) is a load of cables chewed up next to the air box where a pipe feeding into it has rubbed the cables underneath. I work on cables and I sure wouldn't pass it off so I'm gonna repair it and see if that sorts the issue. Because I found it quite puzzling that most people say theirs doesn't even pull when started, mine pulls but then releases

[@LifesAbe-ach]

@@benrampling812 It's knackered... the pwm signalling that holds the motor keeping the cable pulled as gone .it looked firstly to be a diode blown ( small one on rear ) , replaced that to find the chip used was at fault . The chip is a injector chip ( used normally for injection units on fuelling ) it doesn't hold a continuous output signal so the motor looses holding torque releasing the cable .

[@benrampling812]

@@LifesAbe-ach so they put an injector chip in from stock? And because injectors output is momentary and the IMRC needs constant we are both having the same issue? Do you reckon the car has always been this way then? I've been led to believe that the IMRC is closed by 12volts DC and opened by dropping those 12 volts. Which means that most people have a basic continuity problem be it a disconnection or high resistance but in our case we have the Continuity just the wrong chip to support continuous power?

[@benrampling812]

I found a knackered old cable under the pipe from your engine to the airbox where the pipe had rubbed the conductors bare so hopefully that will be the cause, but I can't find anything online to tie the IMRC harness to that specific bunch of pairs. Although I suppose the fault could bridge over multiple components. I had long suspected an electrical fault because I have dashlight and interior lighting problems as well

[@davidchadbourne4890]

Where did you get the transistor from?

[@jpst170]

the link is in the description buddy 🤓👍

[@jarredmccary5895]

Where do you get th transistor

Love the disclaimer to cover your arse.🤣🤣

[@Smilog]

Hello, can i have the specific of this TIP121 please? which i can buy? Thanks

[@jpst170]

The link for the correct transistor is in the description of the video buddy or search '2N6045 TRANSISTOR 2N6045G'

[@Smilog]

Is a single or bipolar transistor? Thanks for reply

[@Smilog]

In the market,on this code, there is 100 v or 80v , single or bipolar, will be nice to let the youtubers knows, by the way, nice video :)

[@smiffdamista]

hiya mate do you know by any chance what causes it not to spring back at 5000

[@jpst170]

what happens is when you start the car the cable then pulls which opens the smaller ports on the manifold and when it hits 5k rpm it then closes the dual stage intake to the bigger ports... if it's not working at all then It will stay closed on the bigger ports. 🤓👍

[@smiffdamista]

@@jpst170 yes mine does not come back from the bumper at 5000 just stays there untill you turn engine off

[@smiffdamista]

@@jpst170 thanks man

[@trayvondiacost]

Can you send me the details of the bloke you’ve suggested. Is his name Brad?

[@jpst170]

Hello mate yes his name is Brad, message me on Facebook @jpst

[@stephenwatson5357]

Is this an emissions fail?

[@antoniosdourvanas1191]

What transistor? photo please.
