QAS Germany: 40 hp gain w/ exhaust system + reflash
Hi,
one of our german forum members has been to "QAS", one of our fovourite tuners. They installed a catback exhaust, hi-flow cats and headers, finally they made an ecu-reflash. The gain in power is about 40 hp (at the crankshaft): 367 PS (= 372 hp) and 380 Nm (= 280 lbf ft). This is our member´s new video: Please note: the co-driver´s weight is about 100kg ;) YouTube - Nissan 370Z 0 - 200 with QAS exhaust system I suppose the run from 0-200 km/h takes about 19 seconds... best regards mike http://img594.imageshack.us/img594/1...133be24.th.jpg |
hmmm 40 HP from exhaust system??
that headers must be doing some bad *** gains! Im interested.. any pictures/price on that headers? |
+1 for pictures or videos. +40hp are insane gains.
|
In for UPDATES...........
|
As I have previously said Mike, VERY IMPRESSIVE! :tup: :tup: I'm not sure if this exhaust is available here in the states. Someone can chime in ....

thats gotta be $3k+ for 40hp at the crank?

Here is what "Silo" (manager of QAS) wrote about this dynorun - I translated it for you:

QAS tuning now confirmed
22nd of Oct: Another 370Z with same setup on the dyno Performance gain 43 PS / 22 Nm (42 hp / 16 lbft) http://img543.imageshack.us/img543/8475/diagr.th.jpg Headers, metal HFCs, catback, ecu reflash After tuning: 359 PS / 374 Nm (354 hp / 276 lbft) |
40hp crank not wheel. Seems about normal..

HI , friends, I live in Italy , I fitted on my 370 a Exoticspeed + Hi Flow Cat , now I will want to reflash the ecu , It's possible with QAS ? wich of ecu reflash you raccomanded for me? Plus , Performance , or V-Max ?
Thank you |
"Vmax" only switches off the 250 km/h-limiter.
"Performance" additionally changes the Target-A/F. This changes the long-term lambda correction, which is necessary to reach the maximum power gain of exhaust-systems and air-induction systems. The engine map wont be touched. "Performance Plus" = "Performance", but w/ changed mapping. They promise some extra power gain. regards mike |
reflash Is what I need
|
Thank you Clouseau , I don't know Duch language , please can you translate this below ?
Unser ECU-Reflash 'Performance PLUS' bietet Ihnen folgende Änderungen durch Umprogrammierung des Motorsteuergerätes: a. Aufhebung der Vmax Beschränkung (Serie: 250 km/h) b. optionale Anhebung des Drehzahlbegrenzers (nach Wunsch) c. optionale Anhebung der Leerlaufdrehzahl (nach Wunsch) d. Änderung der elektronischen Drosselklappensteuerung für direkteres Ansprechverhalten e. Änderung des Target-A/F (Langzeit-Lambdakorrektur welche Leistungssteigerungen von Abgasanlagen, Ansaugsystem, etc kompensiert) f. Anpassung der Zündüngs- und Einspritzkennfelder auf bestehende Modifikationen zur Optimierung und zusätzlicher Leistungssteigerung |
:eek: 2,900.00 EUR = 3,827.79 USD :eek2:

thats all:wtf2:

Sorry for Duch instead of German.
Thank you a lot for translate , I saw f. mod , is only indicate for engine mods, I have only Exoticspeed exhaust system with hi flow cat. and air induction Takeda , I think for Performance step reflash an not for Plus , what do you think about my reflection ? How QSA works for reflashing ECU ? I should send my ECU on German ? an they resend to me after reflash it ? What is: increase of RPM at idle ? Thank you again |

mike *PS: I know CTD-Germany offers a reflash that can be done by sending the ecu via mail. But I cannot promise if you will be satisfied. |
From the time the car started moving until it hit 200KPH, about 16-17 seconds passed. On top of that, the launch wasn't even aggressive at all, so the car is capable of more. This is truly impressive stuff.

Thank you againg for your time and sorry for my poor english.
My car have now Exoticspeed exhaust system + hight flow cat + Takeda air intake, now only need reflash the ecu , but German is too far from me , there are other methods for doing it ? I saw Cobb and Hypertech, but I read that are not for european model, Is true ? |

You could try to contact Mr. Güttler from CTD-Germany - Exclusive Car Tuning & Development; Nissan 350Z, Nissan 370Z, Nissan GT-R, Chrysler Crossfire, Mazda RX-8. They do also reflash the 370´s ecu. You may send your ecu by mail. Link: CTD´s ECU Reflash 370Z adress: CTD-Germany, Tino Güttler, Industriestr. 13, D-47495 Rheinberg phone: +49 (0)2843 169925-0 eMail: »info@ctd-germany.com regards mike |
Thank you very much for your help.
I wrote to Mr. Guttler for reflashing the ecu , I hope he reply the email in english and not German , I will let you know the response. What is the DTC ?? |
Hello my friends, I contacted Mark Gillam of Abbeymotorsport , and it tells me that Uprev Osiris standard, works on 370z european version, I decided now to buy one , they offers also service mapping by a log sended him. It's fantastic.
Great!!! |
