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.

I cannot, yet, but I am hoping to use Mr. Positive's techniques to repeat his work and learn how to do what he has done myself. My 1st aim is to try and remove the flat spot on my z22se. From my research so far it's 5% about being able to get in, 95% about knowing what to change once you are there.

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?

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

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.

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

I agree , tuning products should be better tested than just bolt on parts and wide open throttle.

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.
