We sell SSI and Variohm, depending on the application.

Used a Mazda 6 coil which is essentially a ford coil. These are all "dual output" coils which means that they fire 2 cylinders at the same time so you're running in wasted spark. You give up coil energy and the ability to trim cylinders. I'd recommend running a single coil per cylinder. They all are separate twin tower coils mounted together. Its just that the Ford and MSD can't be separated because they were mounted in the same housing. I would not let ease of diagnosis and replacement drive your decision. If you do your wiring right and are not in a severe heat situation (which is unlikely on a mild NA car like yours) coil reliability issue is not an issue. We run cars at the 24 Hours of Daytona using street car coils with few failures. In fact, most of what's been called "coil failures" were actually harness or connector failures. If you run 4 coils and carry 1 spare, you'll be fine. Another coil I might recommend are late-model motorcycle coils. I've used Suzuki GSXR1000 coils with lots of success. -Neel

Jimmy, Good to see you on this forum! The Vi-Pec will run with a large variety of coils. Ray is right in that the advantage of the LS-1 coils is no external igniter module is needed. The MSD ones will work great too. I've done E30 M3s with three different coil combos, which all work. I've used MSD Blaster SS coils with wires. I've used a Mazda 6 4-cylinder coil with wires (dual output.) I've also used E46 M3 coils to give you fully sequential ignition; they also require igniters. These are really nice and give a stock-looking appearance. Don't let igniters scare you off - they're simple to wire in and don't add a lot of cost. If we build your harness, we'll have all this in there, or we can guide you in doing it yourself. With your application, you really have a lot of freedom because its not especially high-revving, is naturally aspirated and doesn't run terribly high compression. I would look to see something that easy to fit and has good appearance; most modern coils are going to work out excellent in terms of performance. We have the ability to test whatever you choose to determine the optimal settings for use. -Neel

Hey Bruno! I should have checked this earlier! Thanks for buying the VIPEC from us. Let me know if we can help you in any way. Ray seems to have handled all your questions already, but I'll give you a bit of input here.... If you can easily mount a WRX cam sensor and have it trigger once every revolution, I would do that. Sequential injection does have some driveability, idle and fuel consumption benefits. However, if you want you can always begin without the cam sensor and add it later. -Neel

Feel free to ask me about any ECUs. We're factory-authorized dealers for a wide range of ECUs, one of the reasons we're so excited about the VIPEC is that it is a great value in terms of features and performance.

We're having good success with V44 and V88 ECUs on a variety of projects. We're currently involved with a couple of Subarus and have some motorcycle projects coming up, but two of the most unique have been a Honda 650 single and a Porsche 993 Twin Turbo. The Honda 650 is for a very high profile customer, and details will be forthcoming in a few weeks. It has a 12:1 compression ratio and had been a challenge to start due to low and oscillating cranking speeds. This motor has a fairly noisey electrical system and frankly the scope traces of the crank sensor aren't pretty. No problem with the V44 though; we've been able to tame it quite well, and the development is going excellent. Features such as the user-definable reluctor levels and trigger filtering has made it start well where other ECUs failed. The Porsche 993 Twin Turbo is a car with a storied history - this is the LAST air-cooled Porsche to podium at the 24 hours of Daytona. The car came from Porsche Motorsports with a Zytech ECU for which there is no more support; the V88 has slotted in nicely and will provide the owners with years of reliable operation. We're using it with an AIM MXL Pista dash as well as Bosch Motorsports ABS. Apex Speed Technology has built itself on unique and demanding projects; some of what we do can be seen on our blog at http://www.apexspeedtech.com/cblog. We are very excited to be a Vi-Pec distributor and look forward to sharing more projects with the Vi-Pec community.
