Looking for fuel injection system for my FE.

[FUNFER2]

I wouldn't want a nightmare EFI system. Does any stacked/webber,.... EFI company have all the bugs worked out ?

[Great Asp]

Yes, I have the Dynatek injection system on my Superformance. (thanks Stentor).



Mine runs great now (although I did burn out the coil recently)



A couple of things about EFI. First, you have to get around the "Voodoo" of EFI. The system is simple to work with once you get your panties hiked up. Second, you MUST address fuel delivery. My fuel delivery was based on the stock SPF gas tank maintaining fuel to the A1000 pump which it can not. If you buy the DynaTek system, I recommend a surge area that maintains constant supply to the fuel pump. This can be done several ways. But if you have 600 hp on tap and sticky tires the gas in the tank runs away from the supply to the pump with the stock SPF tank. I now have that resolved.

Great Asp's Superformance - FE Build

Now on to the DynaTek system. They currently do not supply a turnkey system that has a FAST ECU, or a wideband O2 sensor. My system has the Pantera ECU, and it has worked great for me. Now Dynaforce is supplying an Accel ECU, and I do not know anything about it.

My car starts no matter what (I just had to update the SPF start switch, but other than that), and idles without issue. Throttle response is "right now", in accel and decel, so you have to be on your toes when down shifting.

Dynaformance was Dynatek. They have been through a bunch of changes, facilities and personnel. Some of the key people I worked with when we (Keith Craft and I) ordered this system are gone. Finding out the level of support, what ECU, and your ability to tune would be key if I was buying another system.

The wow factor can not be beat IMO, it never fails to turn heads at any show I am at.

Love it!

It took me a while to tune it in. The biggest hump was to understand what wasn't working, speed density mode. These manifolds simply do not have enough vacuum. I see all kinds of postings out there from people who claim they work well. They build all kinds of over-sized vacuum accumulators. The FACT is, you cannot get more vacuum then you have by increasing the accumulator in size. You just buffer the fact of quick changing from the map sensor.

When I finally made the jump to Alpha N my problems all went away.

A good friend and I spent a lot of time rebuilding the tables. That included a lot of time in the seat with a laptop logging what was going on. It has been a really great learning experience.

So yes, I'm very happy and satisfied. I don't mind the extra time figuring it all out.

Did you spend a lot time sorting the system after installation?

I asked a very knowledgable Shelby dealer/builder. I was considering taking my dual quad off for an injection system. I was told not to do it. Too much hassle and problematic. Thats what I was told.

I'm staying with my dual quads. They offer the WOW! factor with meat and potato reliability.

I was told the same thing by the owner of the shop that dyno tuned my car. Considering he could have made some money on the deal, I was surprised.

Well, I started my own business about 6 years ago and we have been growing like a weed, without much time to enjoy my car. Over the winter I had a new gas tank built so the car did not run, but I have not been in any hurry to get the car running.

Once the DynaTek guy went to KCMS in Plano and tuned my engine I have had no issue with the system or the engine. I just wish they would have told me about fuel delivery so I could have researched and bought/built a gas tank/surge area while the car was being assembled.

But frankly the system/engine runs without a problem, even though I would rather have FAST and a wideband O2 sensor.

Moral of the story seems to be the FI system can be great if you really know what you are doing and prepared to deal with potentially complicated issues.

For those without the understanding or access to someone who has the understanding your best to stick with the ol' four barrel.
