looking at this post from shiv, he is basically saying that you have to tune your AFR yourself, and the smart will simply compensate for changes in conditions to keep thos AFRs in a 'safe range'

 

I'm well aware of the P0300 code issues. However, if you leave the unit plugged in ALL the time, you're likely to miss other DTC's that might appear. That's not something I'm willing to do at this point. I'm lucky and don't have P0300 issues, but if I did I'd explore a solution that was more interactive.

I thought shiv said that it would not clear other codes automatically. or at least the CEL would come on so you know to check the reader...

But in any case, of course i agree with you completely. it is not an acceptable long term fix.

 

As soon as the CReader is powered, it reads the codes 4 times, then clears them. The Check engine light might still come one for the first minute of driving or so, but will then go off. If this always happens, will you always check? If you always check, then don't you want something a little more slick than a 50 dollar scantool?


...of course, that's just my point of view. I'm sure it's more than adequate for a lot of peolple. I'm just **** about those things.

All primary codes (the important ones) are displayed and unsurpressed. It's on the PO300 codes which seem to be kept quiet. The C-Reader just keeps the stock ECU from completing that particular diagnostic cycle. I have yet to see the C-Reader hide something that should be there in the first place. Once Mitsu fixes this problem themselves, we'll figure out if the C-Reader is needed. But until then, I suggest using it.

Really? That's particularly good news. I had no idea! Where's the difference? Does the stock ECU just do different diagnostics with a scantool attached or is there some bit of cleverness in the CReader that is not documented in the user manual?

CREADER was wasted cash for those of us without the p0300 code and especially for those of us who already had a scan tool.

 

That's a little extreme. It's still a handy tool. Stick it in your glove box, you'll be happy you have it at some point. If you already have several in there already (*cough* me *cough*) then put it in your grandmother's glove box. It'll save her a trip to the dealer someday.

I don't fault vishnu's policy to include it with every kit -- even for those of us fortunate enough to live code-free.

Maybe....

 

I too find the CREADER an unacceptable/uncomfortable "patch". Basically I'm willing to bite the bullet on having to wait for the Xede to load prior to starting the car, but that is at my extreme limit of compromise. I really, really want SMART with all it's advertised features. However, at this point, I'm confused as to which ones are "future" features and which ones are actual active features. For instance, I was to the understanding that the active fueling/timing had a plus or minus authority range, now it seem Shiv is saying that only the negative timing authority range is currently available?
