Vito.FL5 Oil to Air transmission cooler install

[Vito.FL5]

Ok. I´m not having a lot of time lately since I have a 1yo girl, and expecting another one for july. So progress is slow.

But I took the day today to figure out how to install a generic oil cooler I had laying around.

It´s all pre-assembled, but in place. tomorrow I will cut the eccess in the bolts, paint the brackets, and re-do the ugly arse "air pickup" I made today because it looks terrible. But its done either way.

Main reason to do this, is to get rid of parallel systems deviating the water from the radiator, and adding heat to the system.

I plugged this lines, and also the throttle body heating lines. Brazil is hot enough.

I will remove the turbo from the cooling system, but I cant plug it since I need to have some water flowing when the t-stat is shut. To do that I am taking a line from the radiator outlet and connecting it to the water pump inlet, bypassing the turbo. This, together with the cabin heating system water that flows constantly, should be enough to keep the pump fromc avitating and to keep pressure from building up when termostat is closed.

I have the PWR track radiator already, and tomorrow I will instal the HEL oil cooler.

next track event is late march so we´ll se then.

FIrst thing I made an aluminum bracket to bolt it into existing mounting points. (just because it says R somewhere, doesn´t mean sh*t has to be billet lol)

Next thing I made a vent on fender liner. (is this what this is called?)

Then I laser cut a grill.

Yes, I will trim this later

Then I put everything together, and I made a small vent to get some airflow in this area. If that is not enough I will put 2 80mm high power fans in the radiator... But I honestly think this is more then enough.

Looks decent.

Garbage out!

This I like! Great job testing out the cooling system upgrades.

This is awesome! Really looking forward to your results.

Got the engine oil cooler installed today. Didn´t like the kit.

Hoses are a bit too small for my taste, and the rub on many sharp edges, I took a lot more work to get it properly installed than I expected.

but it is there:

I’m expecting the same when I Install mine, modification to not make it rub.

I wanted to ask, how has your transmission cooler mod worked for you?

It did.

I made some improvements after I installed the kit, by ducting the air all the way to the radiator.

Even on a 100F day at the track, trans temp was always under 210F

I´m happy with the rest of the cooling system also and the vented hood also helped lowering temps.

I like your ducting, looks way more efficient

 

[Vito.FL5]

Yes, even being a very small duct, it´s very effective. I never measured trans temps before on the oem water cooler but I as 100% sure it is much lower now. I can feel the shifts are a lot better, speccialy downshifts that rely on the synchros. average trans temps on the track are around 180F so the transmission is very happy.

How are you measuring temps?

 

[Vito.FL5]

Long story short, I have made a patch on the ecu to show ECT2 sensor temps on the dash, where the calculated oil temp used to show. So I can place an OEM water temperature sensor anywhere I want and I have the data on the dash and on the datalog. Its the cleanest way I found.

Now after I have the necessry data on the trans temp and can call the mod a success, I can just tap a sensor on the oil pan and have real oil temps on the dash

ok so this might be the coolest mod. Any chance you can share in more detail how you did this with the dash? I have a physical sensor in the oil pan that reads out on my p3 gauge, but having it on the dash would be even cooler.

If you can bench read/write the ecu I can do the mod for you. But keep in mid anytime you reflash the ecu it goes away because I assume Hondata writes the full code every flash. I could share this with Hondata its a simple patch it just calcualtes a 16 bit value for ect2 and replaces the ram variable for calculated oil temps but I believe Derek has so much on his head this is not something worth spending his time on.

Man if Hondata could add this to the tune it would be awesome. I do reflash the tune each time I go to the track
