Needing some help to resolve an air pump error on AP1

Anyone got any new light on this? Izzy racing now has a kit but it's confirmed it doesn't work on audm.

The GTM kit comes with one

There's a few slight modifications that are needed but nothing major.

Hi I searched far & wide & couldnt find anything that would work. I even asked Bob @ Modifry to come up with something but after a bit of reasearch it was too difficult for him due to the ecu reading the O2 sensors at startup & detecting if the air pump isnt working & bringing up CEL

Can you provide a link to the GTM kit? I would be interested in hearing from someone that has it working.

however it dosen't work on usdm cars, but as aozora said it works on our adm cars and jdm.

whats the point of the air pump.?

**vyets** · 03-11-2011 07:46 AM

it pumps air into the cat to warm it up quicker on startup.

I PM them twice to see if it works on AU S2K with no response. Below is the final thread on their Air Pump Delete Kit post.

If anyone has found a solution please let me know

Hello.

First of all, we will be offering the refund for this kit.
Please send us back your unit, we will refund full price + shipping.
When you send us back, please note following

Please send the kit to...

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.
