Well, start with Dave at Mania to show your support to the nice sponsors for this forum.
Then you can also try Advan Performance, who used to be the Trust distributors, so they know the product and they too have an in-house dyno. Call them on (02) 9648 3366. Speak to Karen or Peter Hopkins and tell them Les in Perth sent you.
The eManage is used a lot over in the U.S. (see here ->
clicky). You can add the injector or ignition harnesses if you require or the boost control kit if you need to control boost (still need a soleniod/valve for N/A cars going turbo though).
Pretty good units for what they are. Get the universal units if you want to get them tuned for custom applications or just that you want to be able to tune something that you paid money for.
Trust do eManage units which are plug-n-play kits for the NA6 or NA8. They come pre-programmed and are a direct plug in to suit:
1) NA6 normally aspirated
2) NA6 mild turbo (5psi boost)
3) NA8 normally aspirated
Although I have heard good things about the MX5 plug-n-play kits, they are not supposed to be re-programmable so there have been situations that customers have been caught out by this
I believe that the last case I heard of was when the customer even bought a new support tool disc to get a new serial/registration number but still couldn't get into the emanage software on the unit. Especially since most of us build a car up gradually with modifications and may need to re-tune the eManage at some stage for different reasons (cams, turbo, supercharger, etc). I think the RX8 guys also had issues with the eManage. However, if anyone knows if this issue has been rectified by Trust and all plug-n-play kits are now re-programmable please let me know and I will edit my post.
I have estimated horsepower improvements from Trust's technical department for the MX5 plug-n-play kits but I'd rather not post them up as they are based on JDM MX5s, on higher octane fuel and on a dynapack dyno. PM if you are curious.
