Should I buy and use the uprev gt mafs? (Soho motorsports air to air kit)

Car specs =soho a2a Vortech si trim. 9psi pulley. 91 octane
Forged engine build


Hello, everyone.
I am installing a2a in Korea.
It's about 90% done and it's soho motorsports a2a product with jwt cam.*
Puli is 9 psi and the engine is forged.
Exhaust is hks silt hi power for bnr34.

The problem is one. There is no reliable ecutek tuner in Korea.T.T. So many people would recommend remote tuning, but Korean and American fuels are different. Ex)ron95 =aki 91 . .

Even during N/A tuning before, an American tuner did remote tuning, but knocking occurred here. And he didn't understand. fuel octane problem

There is only one place that tune vq. It uses the uprev program.*
Under these conditions, should I buy and use the uprev gt mafs?*

In terms of U.S. standards, Korea's high-end oil is at least 91 to 93. The output I want is 500 to 540whp. Boost is 0.8 bar. Approximately 11.6 psi.*

It might be a funny question, but...I really, really, really...It's serious.

A2a is the first work in Korea. There are only seven manual transmissions. The other 200 are all automatic transmissions.*
There are only two F.I. 370z. all w2a

Please help me. 370z is treated like a fashion car in Korea. Your help will be the first way to make Korea more boosted z.

If UpRev tuning is the only reliable route you can go there then get the gt maf sensors.

Thank you so much. While I owned two Zs in seven years, no one in Korea knew about this problem. This is the barren land of Z-Tune.

Who did you have remotely tuning your vehicle from the US? Most decent tuners would be able to figure out the fuel difference and adjust your tune to suit. I'd probably try getting in contact with Seb at Specialty Z or Eugene Turkov (sp?) and seeing if they're able to assist. There was another forum member who is/was in Korea as well so hopefully he'll chime in with who he had tune his car.

vqholic@Korea

I don't know who the other forum members are in Korea.*
The tuner in California used Ecutek for remote tuning.

vqholic@Korea

Thank you so much for all your help.
I sent an e-mail to Sebastian of Speciality z. If there is no way to use the ecutek, should I uprev it, should I buy uprev gt maf and omni 4bar map sensor>?

If you do decide to buy the UpRev GT MAFS, a buddy is selling his in the For Sale section. He's a good and honest guy. Here's a link - 650cc and 1000cc Injectors, Uprev, SPL Toe Arms and Uprev GT Mafs

Seb will take care of you. Seb will have you using ECUtek. No need to upgrade MAF sensors, but he will probably have you get the 4 bar MAP sensor.

Thank you.
I sent him a message.

Your setup will be dependent on what your tuner is familiar with and recommends (as well as what you're able to afford). Discuss your goals/expectations with him and go from there.

vqholic@Korea

Yes. I sent him a message.
Thank you.

Can I use stock mafs when tuning up the uprev osiris? Less than 550whp 12psi

"Z"en

Wouldn't recommend doing so in UpRev.

Your stock MAFs should be fine. I was making 11psi on the topgunz A2A kit on uprev with no issues with my MAFs. I’m switching to SOHO A2A and I’m not expecting to have any issues.

Isn’t the soho a2a essentially the same kit as the topgunz a2a. Soho just copied something that someone devoted a long time to get right. If you want to actually improve your a2a get the topgunz ace upgrade. That is definitely an upgrade that will increase power. You should switch to EcuTek with a speed density tune. Much more accurate. Just my .02
