Another air pump thread.
I´ve been searching but no real answers, a few people wrote that they will try to fool the ECU but no result how it went.
Done this in other car brands and normally pretty straight forward after reading the diagrams. Any idea of the signals going back to the ECU? A certain resitance? Voltage?
Anyone here tried to solve it?

Here is the thread for the one GT motoring was selling.

We are deeply disappointed that we won't be able to fix the issue due to few reasons.
Our unit works ALL-region S2000 except US spec.(which means our unit works on Canadian spec)
Not only US spec S2000 has totally different circuit to control/monitor air pump, it also has different ECU programming to monitor air pump operation(air flow).
Our fix kit was be able to by pass the circuit, but not the ECU programming.
We were trying many different ways to by pass the programming(air flow) last 3 weeks but no luck.
We found this issue very last minute while we were doing long term testing on US spec S2000.
The operation is monitored by oxygen sensor at start up which is almost impossible to bypass the signal/ECU programming due to several circumstances.
Once our original unit is installed on US spec S2k, it causes slight electricity usage even with ignition off due to ECU won't shut off at all.(ECU stays on all the time)
Because ECU does NOT check for air pump operation at first start up after the ECU reset, our unit deleted CEL but ECU kept stay ON.
(However, this is NOT the way it suppose to work. We have tested on other regions S2000 and it works just fine.)
As I said few weeks ago, this kit was originally designed based off euro spec S2000.
After we were done testing on euro spec S2000, we tested on US spec S2000s before the release.
We confirmed that it worked(as it is describe above) which was hard to notice any issue in short period.
Now I really wish it showed some issue right away, not like this....
If you are driving S2000 as a daily, you shouldn't have much issue because ECU only draws very small amount of electricity.
But all buyers are free to get refund.
Once again, we are very sorry to bring this news.
We apologize about all this hassles and issues.

There is no way around the airpump. The one way to get rid of it without the CEL is if you have an aftermarket ecu, or management system. If you dont wanna spend that much, just fix or replace whatever needs replaced.

I need an EMS with OBD still working because of the inspection here. On the same time I just hate crap in the engine bay and don´t want to buy stuff that´s not needed for the engine health.
I´ve removed working pumps on my older cars just to clean up and get rid of hoses.
"No way around the air pump" might be true but worth a try, wont cost anything to try? Got a few really good engine tuners to help me out and if I tell them there´s a market for a simulator they might want to spend some time to solve it.
But I know, it´s probably impossible.
