Syked ECU, 97-99 Neon 2.0L SOHC / DOHC

Read or Write Review

Model Number: 221296-9799DOHC

Years ago, the Mopar ECU was the only option for 97-99 Neon owners who wanted to increase their Neon's performance. It was then discontinued by Mopar around 2010.

Fast forward a few years, and there has been no option for Neon owners, but Kevin at Syked Tuning has released a flash for ECUs that has a similar increase in power and torque compared to the old Mopar Performance ECUs.

Because new ECUs are no longer available from Chrysler, these ECUs start as a used OEM ECUs that are re-flashed with the Syked tune, and have the following benefits:

Gain 7-10 hp peak at the wheels, or even more if your car is highly modified.
Increased Rev Limiter to 7800 rpms
Improved 93 Octane Fuel Maps & Increased Timing
Improved Throttle Response, Increased HP & Torque
No Purge System Monitoring
No EGR Valve Monitoring
No Speed Limiter

Designed for off road use only

This item is purchased outright. There is no core charge, and you do not need to return your OEM ECU.

Note: This ECU can also be used with 2.4L Swapped Neons, but must be repinned to do so.

All Syked ECUs are cleaned with a wire brush and compressed air.

We offer below an option for Connector Condition, what this means, is that we are offering ECU's with damaged electrical connectors for a discount. These ECU's are still perfectly functioning, however they are not in perfect condition. Please check out the last photo in the photo section to see an example of a broken connector ecu that we are offering for a discount.

  If you have done any ignition coil wiring, cam sensor, fuel injector swap then you use the 2.0 pcm. If you have not done any wiring swap at all then get the bolt in 2.4 pcm.

  Its better to just purchase the automatic transmission Neon flash that we offer. However, if you insist on using the manual transmission ecu, your torque lockup convertor will not function and you'll lose gas mileage. Some Neon owners have found a way to wire up a toggle switch and wiring to the pcm to activate the lockup convertor to improve gas mileage at highway speeds though, for more information on that search on neons.org

  If you have a 2.0 liter engine, then it should work. We have no way to guarantee, or confirm though as we all have LHD Neons over here of course.

  We have never tested these on an Eclipse and do not have access to a 420A motor Eclipse to test it on. We can not recommend using this in a Eclipse.

  This pcm is designed to run with regular 93 octane gas. It will still run on E85, but its not a tune exclusively made for E85.

  This pcm is designed for non turbo use. If you were to use this pcm with a turbo you'd have a much leaner mixture, and advanced timing which wont work well with a turbo.

If I have this ECU with my 2.4 and decide to turbo it down the road, can I have someone reflash it for a turbo setup?

  This pcm is not designed around turbo use, its a normally aspirated pcm tune. For your turbo use you should use a stock pcm, or some other sort of piggyback to detune the stock pcm.

  You'll be fine with this pcm and higher compression. However, with that high if a compression you'll need more fuel, and better octane fuel. You'll need race fuel, in addition to larger injectors and regulator. If you don't want to have to use race fuel, get the 10.5:1 Pistons for a more street friendly motor.

  These are used pcms, and sometimes they can be rusty, or have oxidation. We offer a cleaning service for those customers wanting a better looking pcm, and no service for those of you that want a stock, old looking pcm.
Trevor Brunette

When you do the cleaning service do you just clean it to raw metal or is it painted? and also if i were to order it would i be able to get the sticker on the side not stuck on the pcm? thanks

  When the cleaning service is ordered, we remove the backing plate, clean the pcm case really well, and paint it. Please see our photos showing what a normal Syked pcm looks like and then a cleaning service Syked pcm.

  This pcm is great for any engine that is normally aspirated, whether it be stock, or with bolt on parts, or even with cams, pistons, etc. If you want more power from your engine and you want a higher rpm limit, this is for you!

  You can install this on a stock Neon, or with a Neon with cams, head work, pistons, etc. Whatever you have, this will work great. The more mods you have, the more power it will help you create.

It says no EGR monitoring, so does that mean I can just use the EGR block off plates or do I still need he resistor to keep the CEL away?

  When it says no EGR monitoring, it means it doesnt monitor the EGR. This means you can disconnect the EGR system and not have a check engine light.

If I have a 2 door base model 5 speed car with nothing done to it besides a slightly re-geared trans and a bigger throttle body would this work on my car or would it be too aggressive? Also, would it effect my mpg much?

  As far as gas mileage goes, there is not much of a change unless you start driving more aggressively.

  We sell tons of these to dirt/oval track racers. If you want an additional 7-10 peak horsepower, or more than 15 horsepower at redline, AND an additional 600 rpms of power band, these are VERY worthwhile.

  You can use a 97-99 Neon pcm in a 1996, however you'd have to wire in a switch of some sort to control the fans. The 1996 has a relay on the frame rail that controls the fans, and the 1997-1999 has a controller in the pcm to control the fans. If you install this pcm in a 96 you'll need some sort of manual fan switch, or wire in some sort of controller because it will no longer be automatically controlled.

  This is a difficult question to answer.
  
  Ok, Syked makes a 2000 Neon computer flash but we do not offer it. You can contact them directly for that.
  
  If your 2000-2002 Neon is a race car and you only want the car to run, you can install this computer, change some pins around and have it work. The gauges most likely wont work.
  
  The best option is to get a 97-99 Neon wiring harness, dash harness and instrument cluster, and use a 97-99 Neon computer to run your 2000-2002 Neon. Doing so gives you more options as far as pcms go, and 97-99 Neon pcms are more readily available.

In the description it mentions that there is no purge system monitoring. Do you mean no evaporative emissions monitoring? What exactly does "no purge system monitoring" mean?

  Evap/Purge system is the system of vacuum hoses and solenoids on the passenger side of the car that takes the fuel vapors and runs them through a carbon canister under the bumper. Most Neon owners want to remove this system and if you do that, you'll get a check engine light. Whereas with this pcm that does not monitor that function, you will not get a check engine light for that.

  Yes, you need to be using the upstream o2 sensor, so the ecu can determine how rich/lean the engine is running. The downstream o2 sensor is not important, as its only monitoring the catalytic converter efficiency.
