MSP ECU turbo compatibility

[The_big_dill]

Hi there,

I have a specific question which I wasn't able to find a specific answer for when searching, so here I am.

The title does a good job describing what I am asking, but I will elaborate. I was planning to turbo my P5 some time in the future and was wondering what my options/constraints are for turbo selection if I want the car to run on the MSP ECU?

Cheers,

Phil.

I have been told that in MSP ECU is a direct plug in as long as you have a stick shift P5 with a 2.0L. I bought most of the parts to turbo my P5 and the gentleman I bought them from gave me an MSP ECU telling me that that was the set up he had on his P5. I have not started putting my turbo set up together on the car but, I sure hope it is just plug and play.

The ECU should be plug and play.

My concern is more about if the ECU is mapped for boost pressures beyond what it was meant for (stock turbo). Or any other possible issues I may see when trying a different turbo set up.

The ECU comes programmed for 7psi of boost factory and so does the waste gate if you are going stock setup. There might be someone else that has more accurate information. I just thought my answer would help but, I am not a turbo wiz.

No one chips the ecu. When people want it tuned they get the ssafc. When the ssafc isn't enough they go standalone

With our ecu's learning around most tuning devices ( except for the ssafc for some reason) either no one has bothered trying or they failed at using a chip such as hondata

Even if it has somehow or for some reason has a tune it won't hurt it any as it will still deliver the right amount of fuel for how much air is coming in.

Plug it up and run it. As long as your afrs are fine don't worry about it. It will probly run pig rich just like all msps do

Thanks for responding

From what I read, the T25s that come with the MSP are not really re-buildable, so I wanted to see if I can find something more wallet friendly. Not trying to go crazy on the boost either... not yet

Thanks for chiming in.

To elaborate, I do want to go standalone when I turbo. However, If I ever want to pass emissions in Ontario, I need my OBD-II port... So If I can make an interchangeable harness to pass emissions every 2 years, I will need a stock ECU that will handle the turbo.

If not, I will go piggy back.

They're rebuildable it just happens to cost $600-800 to rebuild a ball bearing. If it goes bad I would just get an eBay t25 run it for 20-30k miles and spend $100 to rebuild it. They're good as long as you run the right oil restrictor and use an inline filter. The holes in the restrictor are tiny and get clogged up and that's what kills them

Do a little research on parallel standalone setups

Never doubted the Garretts, but thanks for this tip.

Didn't even cross my mind. This is very useful info, thank you for those key terms
