I put headers on my truck, and i left the egr tube off. now i am getting a p0401 code. i want to know if there maybe some way to trick the ecm to make it think that every thing is ok. can i get the ecm programmed to work with out the egr? i dont want the egr hooked up, because i am about to put a cam in my truck. i would like to find something to fool the ecm. maybe some volts sent back to the ecm? i belive that i have a linear egr. any ideas?

 

PCM tune is your only option. But you will have to have the tuner make the other appropriate adjustments to compensate for the lack of the EGR system. It isn't just an emissions device. It effectively reduces cyllinder temperatures allowing for greater spark advance and more power that without it without editting to correct the fuel/spark maps. Detonation is more likely to occur without a functioning EGR system.

 

OK. thank you for your help. do you know a good company that does this?

 

There are quite a few. If you can find someplace local, it would be the best since they could change anything if you were not satisfied.

I plan on getting a PCMforLESS.com tune for my Rainier. Wait4me is another tuning company that does s-series tunes (sorry no link). There are others as well, just can't think of them right now.

 

thank you. i am checking out pcmforless.com now. they have good prices. i might be sending my ecm in soon. when i do, i will let you know the results.

 

well, i decided to go with wait4me instead. when i get my pcm in, i will let you now how well it works. once again thanks for your help.

 

just to follow up on this problem, i got my ecm programmed by wait4me. the results are pretty good. no CEL. best of all, i dont have any detonation from not haveing my EGR hooked up. idles fine and there are no misses. thanks for your help kyle.
