Fast Intentions Stage 2 TT build by MA-Motorsports.

Mr.Squeeze

They Ecutek we have is different from what the GTR's have the traction control works way better on there cars. We only have Ecutek because of them and get handed the left over race rom crumbs lol.


I knew you would hook with what you have at Pocono next time I'm sure you will be ready

For example the factory Ecu allows Ecu tek to be able to have cylinder cut per cylinder vs z34 can’t do that either all or nothing

Spooler

The other thing I want to bring up is a proper traction control is a safety benefit on high hp cars. 700-800whp car it is not necessary. 900whp and up it is a great benefit. 10k is cheap for a MOTEC M150 compared to totaling the car. Especially for a street/roll race car.

Elmo370z

You will probably start wanting to look into adding sensors to the suspension and data logging during your runs. That way you know exactly what it is doing all times and make little adjustments from there. Also adding a turbo speed sensor to
Monitor turbo speed to make sure you stay within grange of the compressor map.

Spooler

It's Xonarotor, they don't need no silly compressor map. LMAO!!!!

I am not sure what the Motec M150 package can handle. Need to find addition spots for data logging. I do not know if any are available. They will need to be written into the firmware to make it happen. I didn't get that far. My chit keeps breaking stuff.

Elmo370z

All turbos have an efficiency range they work, knowing that ensure you’re not spinning the turbos past what they are capable of. To each it’s own, more data you know the more knowledge you have of what everything is doing.

Spooler

It was a joke dude. The sucky part about Xonarotor is they do not have any maps for their turbos. I hate that chit.

Elmo370z

Not crazy important to have but nice to be able to control from a tuning standpoint. We can’t have that with the stock Ec, GTR’s can with a stock ecu.

Just like I mentioned above we are left with GTR left over crumb with our version of Ecutek.

Hence the reasoning why the stand-alone is a crucial part in staying relevant. Is it necessary no, it cost friendly no. But its a great tool to have if you want the most out of your build and intended to race the car seriously or have a really fun street car and alot of safety features implanted to keep the car from
Killing you.

Spooler

I can say this. I was out of compressor wheel at 25psi of boost. That is when my IAT's started to climb. I ran out of turbine at 29psi of boost. That is when I made 996whp at 28psi and at 29psi I made 1004whp. So, the question is do I go to a 58mm compressor wheel or a 60mm compressor wheel.

Elmo370z

Big as possible. Little lag don’t hurt anything for what you want to do.

Spooler

Then the question is, what will fit without having to build custom tubular exhaust manifolds. Custom stuff isn't cheap at all as you know.

Elmo370z

That’s the question. You don’t have much room to work with. Either you stick with what you have and be happy, drive the car and enjoy it which is what I recommend doing. Or put it under surgery to get a proper pair of twins and be down for an extended period of time. You need seat more then anything, you need data. You’re car has been in the shop since the first build. I’d say drive it, race all next year and then decides if you want to make the journey to upgrading turbos for more power or invest in making what you have now faster which tuning other aspect of the car.

Spooler

That is why the car is at home. So I can enjoy it some before the motor upgrades. It is not cheap doing turbo upgrades as the motor has to come out for that. As long as the funds are available, new turbo's will go on the car. Otherwise I will do my current exhaust housing upgrade that I already have in hands. .82AR to a 1.06AR. Increasing the compression ratio back to 11:1 will not require as much boost as before to get the same whp. I will gain whp no matter what happens. I could send the turbo's back to Xonarotor for a compressor wheel upgrade to a 58mm compressor wheel.
