The 215RWHP run video on a dynojet  

Customer Testimonials:

"When I decided to build my Z I knew two things...I would start with the finest car available, and modify it with the best parts and electronics. There would be no compromises. The project started with a stock low mileage 95tt. It ended with a daily driven, reliable, 410rwhp beast. One thing made that all possible. The Zemulator. Sure the other quality parts made a difference; Greg Dupree products, HKS products, etc.. but what made it all come together was the tuning. With the Zemulator, we were able to totally custom tune my car on the dyno in real time quickly and effectively using the stock ECU. Honestly, I had never seen such an innovative and technologically advanced performance tool for the Z. I watched in awe as my baseline dyno numbers got blown away run after run, tweak after tweak. I realized the true tuning potential of the stock ECU as my runs skyrocketed to 400whp + numbers. All this on stock turbos. To me, the Zemulator is the way to go. I certainly wouldn't have done it any other way."

"When The Zemulator was still in its beta stages it was tested out for the NA Z on my car many a time. Even though I had the Ashspec ECU chip before dyno tuning was done, getting more horses out of the motor was possible with a big hand to the Zemulator. Several test pulls were made between the JWT chip and the Zemulator on the NA and there was a 15 HP difference between the two on my Z. Another very nice thing about the Zemulator is it allows you to run safety maps just like the factory settings. The Zemulator helped a great deal when getting more power out of the engine by just changing settings from the driver's seat!"

When I first started considering an ECU upgrade, Iassumed JWT was the only way to go. But as you probably already know, they are WAY overpriced and lately, the turn around time for this upgrade is terrible. So I started looking into other options. A friend recommended me to talk to Ash. I checked out the website and was going to get the ECU upgrade. Then I saw the Zemulator and quickly realized it was the ONLY way to go. The possibilities are endless with this device. After having the Zem in my car for a while now, I can say I absolutely LOVE IT because of it's ease of use. I am a beginner when it comes to tuning cars and the Zem has made it easy. Besides the Zemulator, is the service that comes with it. Ash put together a very extensive operator's manual which is very clear. Ash has even helped me on an individual basis to help get my car tuned. The bottom line is, there is no other option. The Zemulator is the greatest tuning device ever to hit the market. Thanks for all your help!

"The ZEMulator has many positive aspects. The ZEM has real time tuning, unlimited fuel map adjustability, and the ability to datalog any of the sensors you may be running. All of these allow you to tune the car to the highest possible power output. The hardware is pretty simple install to anyone that has basic wiring knowledge. The software is also pretty simple, as long as you understand the basics of fuel maps, timing maps, and how they work. If you don't, you can learn by reading through the thorough explainations in the Zem Documentation that is included. Congrats to Ash on a fine piece of equipment for the z32!"

"The software that comes with the Zemulator is stable, user friendly and I had no real problems using it. It missed a few convienences here and there, but I have been using one of the first (beta) versions of the software and I haven't tried the new version yet that enables you to connect a labjack DAQ, so you can monitor additional sensors. Specs of my car: twinturboed 1990 NA 2+2. The engine in this car is a '93 NA engine, which had done 110000km before installation. No internals were changed, engine still has a CR of 10.5:1. The turbos, injectors, fuelpump, oilpan, ECU and a few other bits are from a manual '90 Z32TT. This car was tuned using the zemulator for 98RON octane and 13-14psi boost. A ROM image of a similar Twinturboed NA, tuned by Ash Powers, was used as a base. Sofar the car has done 15000km (car is used daily on the autobahn) and a recent compression test reveiled no compression loss since installation of the engine, so the engine is still in the same good condition as when it was installed. I have used the Zemulator and it has proven to be an extremely useful tool for tuning purposes."

I just wanted to take a little time to share my experiences w/ Z1 Motorsports & Ashley Powers. Ash and I had been "online friends" since the earliest days of my project Z beginnings back in November 2000. Ash actually was the person who had custom built my white face EL gauges and he and I spent multiple times discussing my build up plans. I had always wanted to get Ash to spend some time w/ my Z but being all the way in FL i just figured it would never happen. After doing much research & discussing my options w/ roughly 4 shops, i made my decision to have Z1 motorsports do my build up. This was a choice that was made easy when Russell made me feel comfortable in my decision and gave me a very good build quote. Long story short, Z1 completed my build up in late May 02, but i still had much i wanted to tweak on it prior to having it put on the dyno for some real tuning. On day 4 we took my Z to the dyno, it would be a huge understatement to say i was just a bit nervous. My nerves were more like a school kid waiting for his final exam grade, you had done all the studying, all the homework, all the things to get ready for the test, and now the test was here. So we put her up on the lift & Ash starts going to work w/ the ZEMulator & we do a few baseline runs, all normal so far, then he does his magic and before we know it we see 586rwhp before we even spray. This was where my nerves really went through the roof. Ash assured me the car was showing all good signs during the first 10 dyno runs and that she should run very smooth for the NOS runs. Then Ash dials up 20psi of boost, turns on the NOS systems, does more of his ZEMulator magic, and I hide behind my camera while he takes her through the first 3 gears. Then he asks if i'm ready, hesitantly i say "lets do it!!!!" (bad nike ad) and as I watch through my camera display I see the NOS spray & hear the roar of the engine. As I see the spray turn off I turn to the readout & have to double take as I see 744.7rwhp @ 700.2 torque and my jaw drops and I scream like a little girl who just got asked to the prom. I am a firm believer in the work that Ash & the Zemulator are capable of and the great work they are doing down in ATL at the Z1 shop! Ash gave me no reason not to feel 100% confident in his work, and honestly he worked harder on my car than anyone I knew for the past 6.5yrs of owning it.
