Apexi Power FC ecu

[Cupman29]

Anyone know if these are any good for a turbo 172 for boost control and would it even work with an OE ecu?

Cheers

would be difficult. They tend to be configured for a variety of plug and play jap applications, usually running airflow meters. Capable piece of kit, but not really something I'd consider for a Renault. I know plenty of people who've used them on 200sx's etc for years though

Someone was selling one on the Impreza p1 forum I'm on and just got thinking.

Cheers for the input though. I had only heard of them used on hondas and Subaru's but I don't stay too far from Andy Forrest who is a bit of a dab hand at these.

Out of curiosity, what ecu would you recommend for a turbo application?

 

[Dan519]

I'd use a GEN90 personally

Apexi is a good plug n play for jap applications like already said. I used one on my old mr2 but i had to remove my air flow meter to use it. Good live mapping facilities and monitoring. Easy to use.

Doubt ud be able to plug it into a clio as easilly

 

[Cupman29]

Does GEN90 ecu's use only OE sensors or do you need to add or change any for a turbo setup?

Do they only work with MAF sensors rather than MAP's.

you'd need a different MAP sensor, but thats easy to configure

no they work for both types. I did have to change the map sensor though. think to a 3 bar one.

there's different types. L-Jetro or D-Jetro.

 

[Iceberg_172]

yeah one is AFM (L jetronic) other map/ non afm.

problem with the AFM on the toyota was it being too restrictive when trying to "up the power"

everyone always changed to the Revision 3+ ECU and sensor setup. The AFM system didnt like the use of atmospheric dump valves either, quite strange really as you would think recirc would tend to cause problems aswell seeing as the recirc pressure was dumped back into the intake pipe after the airflow meter.

 

[Cupman29]

Sounds similar to imprezas to be honest. They use MAF sensors and tend to have fueling issues with atmospheric dump valves. As MAF sensor has already calculated how much air has passed the sensor, if this is then dumped the ecu has already calculated how much fuel has to be added and so causes issues.

Cheers for all the info.
