Do you need to replace your car computer? Have an annoying problem or erratic behavior presented by your car, but it is intermittent and no mechanic has been able to fix it?

Did you know that it could be caused by a faulty car computer (ecu)?

And no wonder, since now a days the ecu is responsible for everything that happens in your car's engine. It takes care of ignition timing and distribution (yes, cars no longer use a distributor nor points and blades), it takes care of fueling (yes, no longer a carburator is used), it also takes care and replaces the function of many accessories that are part of the past now, and yes, it even takes care of the security (anti-theft).

Replace it now and get rid of that annoyance once for ever!

We have discounted and done everything we can, in order to offer a superior quality unit, still at a very affordable price, if not the best price on the Internet.

You no longer need to pay extra to get your car up and running again!
