I know this sounds real ghetto, but does anyone think a air mattress pump work as a replacement for the secondary air injection pump? If i rigged it up so that it would get power from the original source. and hooked up the hoses to it would it work?

 

All the Honda pump is, is a glorifed air mattress pump. I feel your pain on the Honda cost to fix this ####er. The problem is that it pushes a specific CFM and has fittings for those specifically chosen hose diameters. You'd likely have a pump with much less air flow, and turbulence in the tubes.

 

ahh thats what i was wondering, about the cfm and if the computer would know

 

Great idea if you can get it to work. Somebody please come up with a air pump delete fix. The Chinese can hack Google but nobody can hack the Honda ECU????

 

There is one. Check the sponsers forum

 

Send GT Motoring a PM, they might have a fix for you. It doesn't work on US spec cars though.

 

It doesn't work on any car AFAIK. I don't have access to Euro spec electrical info, but on the US spec this kit WILL NOT WORK. They are supposedly working on a fix.

FWIW the ECU looks at the primary (and possibly secondary) O2 sensor to determine if the pump is working. I have tried, unsuccessfully, to spoof the signal and fool the ECU into thinking the pump is there. It does this in addition to monitoring the current through the pump which is easy to spoof.

 

Anyone thought about tricking the ECU into never seeing a cold engine so it just never goes into that part of the cycle? Is there going to be a problem with the ECU missing the cold start? As I recall the high idle on a cold engine is done purely mechanically. What would happen? Rough idle when cold? Why does the ECU run a cold engine so rich?

There is also the question of the ECU validating the presence of the air injection pump components with out going into the mode where it is operating. I confirmed that when I unplug my ECT on a cold engine the pump will not come on. This is a very easy connector to get to - is anyone willing to try running their car with out a smog pump through a few start/warm up cycles to see if it can keep the CEL off? Please don't drive your car like that and it is not a permanent solution but it would be a good test to see if there is a show stopper with this technique.

 

interesting discussion, lets keep this going.
