Which ECU ???

[smorison]

yes
both kaveman (gr) and myself (gpx) run them ...

considering that you really only need to tune timing and a/f ratio there really is no need to go further unless you are putting on a turbo or something else - that said it does a hell of a lot more if you want it to.

if your in sydney UAS have experience tuning and installing them (they can be a bit of a challange to install)...

I don't know, I don't really want to run a piggyback ECU I rather go standalone, I thinkin of getting a Microtech LT12s, just get it to manage the fuel and ignition, and leave the rest for the stock ECU, thats whats on my mind unless something else catches my attention.

[FTO338]

What is the point of getting a stand alone when all you do is using a piggyback function?

Unless you running some serious power, 300kw+, then i don't see the point of getting a stand alone ECU.

Well ive booked in to get the exhaust done next monday and looking to get the chip put in on the wednesday... Im leaning towards the Unichip as local dealer can put it in. I still may go with the Greddy depending on price.

[barfy]

Does the unichip override the speed limiter ??

[Bennoz]

Yes

Well ive bit the bullet so to speak and gone with the Emange i decided to go with the best tuner available and he just happens to tune the Emanage... Afterall you can have the best ECU out but if the tuners is crap then so will the gains. Anyway he specailises in Mitsubishi's so i decided on him...

For you local people im going to Graham Wests, i will post dynos before and after the install...

I guess that (FTO338) has a point, maybe going piggyback is better, in that case I'm looking a the perfect power SMT6 and SMT7.
On the web site it looks like they are two different things because it says "The SMT7 and the SMT6 are going to run parallel, as there are differences between the two products that make them both handy tools", would anyone here be able to explain the difference, I thought the SMT7 would of had more features.

[smorison]

the biggest drawback for standalone units is you loose driveability... there is a lot more going on in the standard ecu ... its not just running your engine...


the SMT6 is more than adequate for everyone's needs unless you are running turbos and other silly things like nos.

[bigpitty1]

Things that I'm looking for is if it can record data from the engine, remove the speed limiter, adjust the rev limiter and the other regular things like adjusting the fuel and ignition MAP's.

[khunjeng]

you can do that with the e-manage - I have got mine on order. Essentially all u really want to do is adjust fuel maps to make AFR more consistant and if u have some extractors start advancing the timing..this assumes u are running a N/A car of course...go with what your tune guys suggests as its likely he knows that unit well...in the end I doubt there is all that much differrnce between the basic models of the unichip and the emanage...I know I got my emange + 2 harness' for less than $700 if thats any help on price comp.

[bigpitty1]

I have read some where that the e-manage only can adjust the fuel a 5 preset RPM points.

[khunjeng]

you can upgrade it if necessary:

"e-Manage is an inexpensive programmable fuel management system that allows you to properly tune your factory fuel system without having to change the entire factory ECU system to an expensive ''stand-alone'' unit. The e-Manage system is a universal ''piggy-back'' type unit which taps into most Japanese factory ECU wiring, by utilizing the existing sensors. Basic functions will allow the user to slightly alter factory injector duty-cycle (± 20% at 5 preset RPM points) by intercepting and altering airflow or MAP sensor signals. For Honda VTEC YO!!!!! cars you can adjust the VTEC YO!!!!! shift point. Additional features are built into the system but are only accessible through the use of the e0-1 programmer or our PC-Windows based ''e-Manage Support Tool'' communication software (Please see our Authorized GReddy Support Dealers for more information). There is a 16x16 airflow adjustment map, larger main injector correction adjustment, upgrade air flow meter adjustment, boost limiter cut, anti-engine stall, VTEC YO!!!!!-fuel adjustment, real-time map trace, real-time display, real-time communication and basic Data-logging. With the use of our ''Optional Injector Harness'' and the software, the unit has the ability to control an additional 16x16 injector duty cycle map and the controls for adding up to 2 additional sub-injectors. If the ''Optional Ignition Harness'' and the software are used the unit has the ability to control a 16x16 ignition timing map. All of the above maps can also be map-traced in real-time as well. If the factory range of map or airflow meter is surpassed, you can incorporate our ''Optional GReddy Pressure Sensor and Pressure Harness'' to set larger scales of adjustment. All installation and tuning should only be made by a trained technician with proper air/fuel monitoring tools. (Some functions may not be compatible with some applications.) "

I'm not sure about what sort of record data you after, but the basic Apexi SAFC & RSM will remove the speed limiter & rev limiter & it does have some data record function too. On my last dyno run, my car got up to 192kmph & it also saw 9500rpm at one stage (Not a good thing to do if you car is stock)

[bigpitty1]

Thanks for that info on the e-manage khunjeng, the e-manage is starting to look better, I will do abit more searching though but I am planing to turbo in the future, nothing major like a complete engine rebuild I just want to make sure that a piggy-back ECU can do the job.

FTO338, thats pretty impressive doin 9500rpm, data that I'm look to record is like the engine RPM, throttle position, A/F ratio etc in different situation.

Thanks for your help everyone.
