DTAfast designs and manufactures engine management systems for spark ignition engines intended for use in competition vehicles. All our systems are easily mapped and are very competitively priced. The systems are designed to be fitted to almost any engine. Usually on a modern engine the existing crankshaft and other sensors can be reused. If this is not the case then we provide a full range of temperature sensors, crankshaft sensors and wheels, pressure sensors etc. Our systems are in constant use worldwide and countless competition successes have been recorded from club to professional motorsport, including motorcycling, jetski and snowmobile racing. A number of multi-national motor manufacturers use our systems for longevity testing of their engine components because of their transparent ease of use and their ability to stress an engine outside its normal operating envelope.

Retropower have built another monster. It's an Opel Manta you say? Well, yes, that's correct. But how many Opel Manta's have you seen that have an RB25DET in? 425bhp and 352lbft of torque! #DTAFast #S80Pro tucked away neatly, doing the business.

This is a long post. It's about injectors, and why you should only buy from trusted suppliers. #DTAFast dealer and VW 1.8t specialist Badger 5 Ltd recently received a set of injectors from a customer to fit to a car. It instantly ran terribly, so the injectors were pulled out and tested on the ASNU Fuel Injection injector tester. This was the result: https://www.facebook.com/Badger5Ltd/videos/1584198735031539/ That explains the rough running then. Now, our ECUs are good, but not even ours can help with that! So, we decided to send him a few sets of injectors that we use. First up, the ever popular Siemens Deka 630cc injectors. These are getting quite old now, but the results were pretty much as expected: https://www.youtube.com/watch?v=BZmb4E5_iH8 All 4 were 606 to 612cc at 3 bar. Next, our Bosch 1000cc injectors. This is the first batch of these we've had, but we trust our suppliers. You can see why: https://www.youtube.com/watch?v=ryopKAFBFKQ They were all 876cc to 888cc at 3 bar. Finally, the very well respected, and ever popular Magnetti Marelli Pico injectors. These are the 12 hole version for extra atomisation. Look at the results! https://www.youtube.com/watch?v=Phg2jxFnbjg Super consistent at 496cc to 500cc at 3 bar, As you can see, all our injectors are the real deal. We will only buy from trusted suppliers, and while we could probably get them cheaper, we would rather know what we are selling to you. As the old saying goes, buy cheap, buy twice.
