Hi all, im considering upgrading my stock ECU in my FD RX7 to a Wolf 3D. Just thinking over a couple of things right now, one of which is, do you still get error codes out of the Wolf like i do on my stock one?

I understand that the diagnostic port i currently use for my stock computer would probably be defunct with the new computer, but my stock computer has alerted me to possible problems with solenoids/etc on the car before, and i was wondering if the Wolf would do the same thing (or is it up to the driver to just figure out this stuff themselves?)

error codes as in o2 sensors bad and such? if thats your question, no.

however you can easly tell by looking at the outputs from your sensors if they are good or bad.

with a stand alone you can by pass the solenoids, go non sequential, or single turbo.

I personally have a Plug in unit too, and I wouldnt change it in the world!

Yup 'CrackHeadMel' that is exactly what i was talking about...

Ok, so if im understanding you correctly, your computer will display the voltage levels coming from the sensors in your engine bay, and the state of turbo system control solenoids, on a 'live' engine. I.e you will be able to see the voltage level coming from your O2 sensor, or be able to see the state of one of your solenoids?

'Signofinfinity' you raise some good points, but would you mind elaborating on them for me (im still a bit new to how the FD works and the mods you can do with an aftermarket ECU). Are you suggesting i can totally bypass the sequential operation of my twin turbo setup so it acts like a single turbo? I have had some problems in the past with the sequential turbo setup, and the solenoids that control it, so i would gladly get rid of the complexity of the sequential turbo operation if it was possible. I probably dont wish to go single turbo just yet though, cost is one reason why, the other reason is my car is my daily driver so i dont want it off the road any longer than it needs to be.

Thanks for the great info CrackHeadMel and Signofinfinity!

well, i ran succesfully a non seq setup for a year or so. not much difference from the seq just a tiny bit lagyer.

Yes you can totally eradicate your solenoids and stuff going with a stand alone and non seq. No internal mods are required to go non seq. There are a couple of sites on how to do a quick, cheap and cost effective conversion. yes the non seq in a way are like a single, just not as efficient. I boosted 24psi easily, twisted my engine and melted a couple of rotors with the stock turboes. you can pull out some punch of them anytime. they are not as reliable a a big single.

I am rebuilding now with a to4r. but i never used any solenoids....

hope this clears stuff a bit

Hey thanks George, i totally understand what you are saying now. I iwll certaninly go look for sites on google (and look in amongst the other posts on rx7club.com) for information on how to do this. Do you have/remember any particular links which you found were most helpful on the subject of non-sequential conversions?

Thanks for any more help you can give me, and i really appreciate your info so far!

If you search in the 3rd gen subforum of this website, you should find it easly. it has been covered there many times.

Love the link!

Ha ha cant believe how simple the non-seq setup looks - its like christmas morning all over again :-)

You made my day CrackHeadMel...
