ECU options that work with Opel Cars

[SilentShout]

Greetings all

Moving forward with my turbo build, i am looking into options for engine management, I did previously start a thread on piggyback options, however im opening it up to all options including standalone.

To narrow it down im interested in aftermarket options that work with opel cars.

Options I have been looking into are as follows:

Crude
RRFPR and an extra injector + controller, very crude and high chance of it going bang so definitly steering clear of this one

Piggyback
Greddy emanage ultimate - interesting level of control for a piggy back unit, reportedly being able to control both fueling and spark retard, ideal for turbo applications however more aimed towards JDM cars.

AEM FIC6 - Another piggyback unit that allows you to control both fueling and timing retard, however much more user friendly and more options for instillation, Works with both hal and mag types of sensors, And you can upgrade to larger injectors and just enter the percentage size bigger and it automatically adjusts all the maps to suit so it will still run like factory. Also works with a few different aftermarket o2 sensors, specifically ones that are wideband, and mimic narrowband output to keep the factory ecu happy. If i was going for piggyback, i would go with this.

Standalone

Anything haltec seems to be really good for GM cars, however at is core the corsa c is european so i am unsure if it will work. The issues with standalone is there is only one ECU i know of that works with EPS (the sprint ultimate or something like that)

Incredibly expensive to install and tune, also very time consuming as the car will need to be rewired from scratch, the factory ecu may even need to stay in to control the dash etc due to the immobiliser.

Other

Getting the factory ecu flashed would be the easiest option due to no rewiring required, however with no one in Oz catering for it, and the great ecu hack project at a permanent standstill due to siemens programming being a B*tch it would be difficult to organise a flash with my ecu most likely having to travel across the globe and back.

If i was to decide on one, the AEM FIC6 is the way i would go, at $450 it would be the best bang for buck option for turbocharging the car. however i am told from some people it wont work with the engine even though it covers both types of sensors. Alternatively if i can get in contact with Warren G maybe he can do bench flashing, havnt tried contacting him quite yet due to easter etc, soon though.

Has anyone had any experience with aftermarket ecus and their opels? any opinions on what to steer clear from etc? (besides a crude setup as your gonna have a bad time)

If it helps I asked a well known tuner in adelaide about a custom tune for my Z20LET and was told a unichip piggyback ecu was the go, I'm not so sure about the specifics of features and the like but seemed to have some goodies like remapping throttle response with the fly by wire accelerator, launch control and mapping our cat errors. He showed me a dyno map of a Z20LER he had just done with really good gains, quoted $1850 to buy, install and tune

[SilentShout]

Interesting, i havnt heard of unichip before but ill check it out. Fortunately the z20let ecu is a bosch motronic and if i had one of them i would already have the ecu files cracked for it. Unfortunately siemens have made their ecu rather cryptic meaning the simtec 71 in my car is uncrackable without a bench setup. Ill look into the unichip though as the fly by wire throttle is where the 1.8 runs into trouble with aftermarket options iirc. Thank you =)

Update: is this the one you were talking about? http://www.dastek.co.za/about_the_unichip.htm

Website hasnt been updated since 2010 and its a south african company from what i can see.

The only other option was a european Unichip site however it only spoke of remapping ecus and the only opel/vauxhall they listed was the 1.9 ctdi engine.

I wasn't told anything by the guy other than the name of it but assumed it was the one here: http://dynomotive.com.au/unichip
It doesn't say much about compatibility but I guess he knew what he was on about haha, he said it was easy to remove and install if you got a new car so assumed it was fairly universal

If you want to know about standalone options, talk to @andrew. I believe he's running a Haltech unit on his SRi.

if you wanna know some options (also about tunes using the original ecu) go to Cleveland, just around the corner for you. Bayside Performance Services (BPS) and talk to James. I warn you though that it might not be cheap.

[SilentShout]

Cleveland is a good 1hr 40min drive away from me granted theres no traffic, and I already sent 2 emails enquiring about their tuning services in regards to the sri, havnt called yet but the few other mobs (chiptorque etc) closer to home that i spoke to either laughed or genuinely didnt know what to do even if i spoon fed them all my findings in my ecu hack project =(

[poita]

Had a Link G4 Atom installed in the calibra. From memory was about $2.5k. That's the unit, fully installed, car dynoed and tuned to suit. The standard ecu was kept to run dash functions, immobiliser etc was taken car of by a mongoose alarm system

James tuned my old car, he's extremely knowledgeable . 1hr 40min is nothing mate, further for me.

I had bayside do me up a quote they said $1750 for ECU, allow $700-800 for install, $450-$550 for tuning and $100-$150 for plugs and pins etc. Give you an idea, to tune the factory ECU will run $1200 for first 4 hours and $165 per hour after that, that was for a haltech ps1000

Haltech have a better ecu for the corsa c's now haltech elite 1500 which is more compatible with our engines, cost $2300
