Are you joining this groupbuy?

[Solid]

Nah, I already got all those gauges, just passing it on...

[TaZaM3]

Hmm interesting. Anyone know more about the product?

[iLLM3]

I would also like to know more!

I was just looking into getting some defi products and this seems like good alternative. Some questions stuck in my head though. Maybe someone will be able to help me. So, if I want to have both AFR and EGT then I will need to weld 2 adaptors(?) into exhaust, yes? And for correct reading they should be before cats, right? So this will involve removing headers as there is just no space to weld on the car. Or can I replace one of oem pre-cat oxy sensors with wideband sensors and let dme read it's reading and also connect meter to it?

Yes, you'll have to weld bungs in for both the EGT and Wideband AFR sensors. You could replace the OE one pre-cat and have it send narrowband singles back to the ECU, but personally i think a new bung is easier and you have less change of giving the ECU bad readings. I have both of my sensors post cat and all the readings seem fine...

I just read some texts about afr sensors and allmost all of authors say that afr sensor should be placed before cats. I'm not sure why, but one purpose of catalyst is to do CO + O2 = CO2, so there going to be less O2 after it, so afr readings can't be right then. Am I wrong here?

What i was told is that even dynos take it from the tail pipe, so it shouldn't matter. Mr PaddleShift also had some snazzy forumlas to help prove that it didn't matter. I read 14.6 on my wideband while in closed loop, so it seems pretty accurate. Also, throughout the rpm band my afr matches what my dynos read exactly.

Thanks for your help. Seems like I'll stick to post-cat too.

looks hot .. hightly interested.

Yea, if i were to do it over agian, i would have went with this solution.

I spent $350 for PLX wideband gauge and controller alone... Another $200 for the Greddy warning boost gauge. You can see how it adds up real fast.

[GBX330ci]

but where would you mount that thing?

[Solid]

It's so damn small, you could mount it almost anywhere
