Any ideas on what i would need to do to get the power fc working in my car again? Could there be a faulty sensor. Asg said they could go through the wiring but would charge me by the hour and i dont have heaps of cash to play with at the moment.

Any ideas or input would help cheers

Basically the story is i got a power fc installed and tuned at asg which cost me $500 and made 241 hp on their dyno

it worked for 4 days before it wouldn't start. The rac came out and said it was either ignition switch or immobilizer. I had an auto sparky mate come and and said the ignition switch was fine, i then removed the immobilizer myself. The car still wouldn't start.

I then got it towed back to asg. Where they plugged in the stock ecu and the car started running. They then tried my power fc on a different car and said it worked fine. They said the wiring in my car was probably faulty somewhere and if i wanted them to start looking it would be something like 120 and hour. After just spending 1200 on buying the power fc and tune i was broke and couldn't afford this as it could have taken many hours until they found the problem.

I started this exact thread to which mao pm'd me to bring it in. I then drove it on the stock ecu to evolutionr. Where mao stated that asg had tuned it on a faulty afm. Which he then replaced and retuned.

Hi guys my name is rhys i got my power fc tuned and installed into my red gc8 wrx there about a month and a half ago. This cost me $500



it wasn’t running as smooth as i had hoped, it lasted for about 4 days before the car cut out on me and i had to get it towed back in. You guys then put the stock ecu back in, but said the power fc worked fine on another vehicle, and there must be a wiring issue with my car.



I decided i would take it elsewhere as i wasn’t happy with the service that you provided. After inspection by another workshop i was told that the car had been tuned with a faulty air flow meter. I have no idea how you guys didn’t pick up on this before you tuned it as the air/fuel ratio wouldn’t have been correct. After replacing the air flow meter. Here are the results of the first power run on the tune that you guys done.

177.6 hp and 227.43 nm torque which is nowhere near the power it should be making based on similar vehicles with the same modifications.



I then spent another $450 at the other workshop on a retune as yours was done so poorly. This is the graph after the re-tune.



http://i1111.photobucket.com/albums/...r/dsc05857.jpg



as you can see 264.2 hp and 344 nm torque. This is where the vehicle should have been at when i got it initially tuned with you guys.



For this i am requesting a refund of the price of the tune (not including installation ) as the service was not up to standard.



This should be a reasonable request, as per the information on this website

refund or cancel service - consumer protection - department of commerce

thanks. I look forward to hearing your reply. Rhys

1 - your car arrived to us to see why it wasnt running with stripped wires hanging out of the dash everywhere which i told you and you agreed needed to be cleaned up. Obviously between us tuning it and you bringing it back someone or yourself has pulled it apart and done whatever looking for an issue or perhaps creating one. Your car didn't run so we plugged in the stock ecu and it ran. Then we plugged your power fc into another car to check and it ran. This took 10 minutes to do and you were then advised of this and we suspected a wiring issue as both ecus were ok and your cars wiring was a mess. Due to our current work load we were not in a position to fix this and you towed it away. Whether it was the wiring or not i don't know as we never went that far with the diagnosis.

2 - if your car did have an afm failure it was after the tune as it would have failed somewhere between the moment you picked it up on the 15th of october and 3 weeks later (not 4 days) november 5th when you towed it in for us to look at.

3 - looking at your 177hp curve i would guess that it has been run up with the boost turned down to give a low power/torque figure. This is typical of evolution r but not very smart as obviously we have records of the last run done on our dyno. The curve is unusually smooth for a car tuned with a faulty afm. If we tuned it with a faulty afm it would be so rich or lean it wouldn't rev with new afm. It would be interesting to see the boost/afr power curve of the "177hp" run.

4 - attached is the chart from the last run done on our dyno. You will see that it made 241hp and 314nm - bit different to 177hp and 227nm. There is also a mixtures chart showing afm working correctly at the time of tuning.

5 - your new tune also appears to be about 500rpm laggier. Have you changed anything or is it just tuned poorly? It appears you would be running more boost due to the peaky torque curve which would explain a difference in the peak figures.

Look forward to receiving furthur documentation from evor regarding this.

Feel free to forward this to all parties/communities involved in this argument inc public communities you have mentioned


thanks
