Vx220 Ecu Binary

Oliver has been created as I merged many of my scripts into a single program. It makes the OP-COM livedata analysis much more easier (not only for Z22SE). Currently running only in Linux. More info here.

Thank you.

I'll translate it and read it over at the weekend.

I've downloaded Oliver, but i'll have to set up a Linux VM. Will it work with Ubuntu?  If not what are you running?

The new laptop is on order.

Ubuntu should be fine. I use Mint.

I have finally got the laptop up and running.

Windows 7 seemed to be the best for the MPPS v16, and I also have some other pieces of software for other things that might be useful.

I will have the VM and Ubuntu installed tomorrow, and then I can start looking at data (hopefully), and get you a binary.

Who on this site can map / alter the vx220 ecu.

Can't wait to see your experiences.
Unfortunately I had to suspend my testing for a while because of a slave cylinder issue. I'm still waiting for the fix.
However I updated Oliver (v1.1) in the meantime. Customization capabilities are improved in "table" and "2d" modes, and a realtime mode is implemented. The latter can be used during livedata recording.
The latest post has been updated with the changes, and the download link can also be found there.

I'm able to do some modifications described here before. What would you like to alter exactly?

VXT ecu. Lean at 4100, then goes ok beyond.

First of all, I haven't seen a vxt binary yet. I don't know whether it has similar structure to the z22se or not.
Technically to be able to make any changes you have to do checksum correction (except if you have a tool that can do it). But this would be only the very first step. Then you have to identify the proper map(s) and modify it accordingly. Most likely a lot of time and testing will be necessary, and the outcome is uncertain. If you want a quick win, you have to contact a tuning specialist.
I can check whether the z22se checksum calculation method is appropriate for the vxt if you send me a sample binary.

on the NA , the remap only really increased the rev limit

unless you dramatically change the intake side of things to increase flow over the throttle body then you won't see any benefit

I don't think there's such a thing as THE remap. Remaps can be quite different, and there's no requirement for a rev limit increase in it. Beside power driveability, driving comfort, fuel efficiency can also be improved with a remap. I'd say these are benefits either.
 

the vx220 z22se ecu had a reduced rev limit from the factory, something like 6300 rpm

A simple stage 1 remap was basically just an Astra map with the increased 6800 rpm limiter

Mr Positive

i managed to read the ECU and get binary.

I've sent you a PM

Depends on many other things... Just ramming more or less fuel in, or more or less spark wont help much if the intake manifold is the actual problem.

yes , it quickly becomes a task of diminishing returns , the best you can do is get in the sweet spot for lambda and most combustion efficiency for timing, whilst keeping some margin for component protection.

I've got the binary from blackoctagon (thanks), and found that is almost the same as the binary I had before. Only a few map differs. Moreover in the meantime I've also got an official Speedster/Vx220 binary from TIS and that is exactly the same I had. I'm a bit confused because there are a lot of differences between maps for the Speedster/Vx220 and maps for other cars with Z22SE (Astra, Vectra, Zafira). E.g: It seems the AFR is much leaner than the others, and the EGR is also much more active in the mid range.
Are there any differences in the Speedster/Vx220 engines or in the externals? I know only the missing aircon.

I also managed to completely disable the EGR (activity and fault code), and identified the part of the code that generates all the fault codes. Details here.

maybe torque reserve to run the power steering , but that would be a function of ignition timing

Ok, thanks. Maybe you also know whether there were different versions of firmware or factory changes for the VX220?
