Eclipse 420A ECU Performance Flash 1995-1999 Eclipse Non Turbo

Eclipse 420A ECU Performance Flash 1995-1999 Eclipse Non Turbo

Syked ECU Tuning has released a calibrated ECU for the 1995-1999 Mitsubishi Eclipse Non Turbo w/ manual transmission. We have not tested this ecu on an automatic but we are fairly certain this will work fine on the automatic if you want to try it out.

If you already have bolt on modifications with your 420A Eclipse, this will help give you additional power and torque! It's a simple bolt on part that is ready to install once you receive it.

What you can expect:
  • Increased rev limiter to 7800 rpms
  • Advanced timing tables for faster response and acceleration
  • Improved fuel tables for safe power, even with additional modifications.
  • Removed speed limiter at 118mph
  • Gains of 7-11 peak horsepower. Nearly 22hp gain at redline, because power falls off rapidly with the stock tune.
  • This ECU flash is designed for race car use - ie, dirt track, oval track, road racing, auto crossing, etc. If you have a street car, please call us to discuss further.

    In order for this flash to be done you will need to mail your ecu to us. Package it up well, the plastic connectors break easily where the wiring plugs in.

    (This is our return form used for customers to return items for refund, but it still asks you for all of the important information which will help us write up your order faster. The form also has our shipping address on it as well. Our return form asks for your order number, but since you are placing a new order, disregard that section.

    Once we receive the ecu, we can flash your ecu in house and ship it back within 2 business days. We typically ship back to you with USPS Priority mail service.
    This is our address: 9531 Town Park Dr, Houston TX 77036. We have been at the same location now since 2001. Keep your tracking and after we receive it, please call us so we can more quickly turn your computer around. We will ask for a credit card by phone for payment.

    Total cost is $300.00 for the flash plus $15.00 return shipping within the continental USA. Shipping to Canada is about $60.00.

    Note - pictured is a 96-99 Eclipse 420A style ECU. The 1995 Eclipse 420A ecu's are much smaller in size, but we can still flash those as well for the same price.

        We do not offer any ecu repairs, we only flash with the performance program. We have seen some companies offering ECU repairs on Ebay perhaps check those out. Or, buy a spare used ECU, make sure it works in your car, then send that one to us to flash.

      Where can I purchase an ECU for a 99 eclipse non turbo so that you guys can perform your magic?
      I'm thinking about keeping my original unit for smog check time.
      Modified units can be picky sometimes.

        A quick search on Ebay, and we found a bunch of computers for sale. We typed in Mitsubishi Eclipse 420A ecu, but you can type in pcm, computer, brain instead of ecu for search terms.

      Hi there! I have a 1998 mitsubishi eclipse 420a. So far its got cold air intake, headers and I'm having the head shaved, ported and polished. I do eventually plan to put in a set of Brian Crower s2 cams. This will be an asphalt circle track race car. With these physical modifications along with an ecu flash, what hp gain are you thinking I'm looking at roughly?
