You sure it's a p0104? That's a generice obd2 code for the Mass Air Flow Circuit Intermittent, which MINI's don't have. We have MAP sensors.

Ever since I put in the 180* t-stat I get the code p0128, which is a MINI specific code for Coolant Temp Below T-stat regulating temp....but only when it's 60* and below outside. I have MTH also.

 

Make sure the cooling system is properly bled. There is a bulletin about this causing coolant temp faults.

Wagnbat, I have mth and that may be helping with the codes. I also have the bypass valve tied shut and no codes for that after 4 months. My stock car did get a code for the zip tie trick, so I'm curious how it will react to the t-stat.

Keep us posted on your codes.

 

I have a m7 thermostat and haven’t thrown any codes b/c of it. I installed it sometime last fall and ran it through the tough winter of the north east. The only issue that I had was the engine not getting up to operating temp. If I was on the highway when it was really cold, it would never get up to temp. When it's warm out it will noticeably operate cooler than stock, just my .02 Hope it helps! -- Johan

 

I forgot to ask this earlier, how does the gauge read? Still read normally in the middle?

 

Bmw temp gauges are dummie lights and don't represent a direct relationship with the actuall temp other than cold, operating temp, and too hot.

As for it heating up any slower, It should get to the opening temp of the t-stat at the same rate as the stock unit. Once the m7 t-stat opens it should maintain, while the stock unit would continue to heat up until it's opening point.

 

My bad, it is P128, and I don't have MTH. Data from OBDII reader:

P128
2701 RPMs
71 IAT
178 COOLANT TEMP
61 MPH at the time it went off.

So the coolant temp is 178, which is obviously right next to 180 which I believe the M7 should keep it at... This is the same temp I was getting last week when I was riding around with John Behe in my car with an OBDII hooked up.

The codes are a bit more sporadic now... During the winter, I couldn't go a day without them coming on, and now they come on almost randomly every couple days.

That was another thing John showed me... Once the coolant temp reaches a certain point, the gauge on the dash is in the middle. I think it's about 150-160 degrees... The temp kept going up to near 180, and the gauge didn't move after a certain point. John said it should be a light indicator, because it would do the same thing...

 

Which Palm scanner are you using? I'm searching the Palm web site (http://www.palm.com/us/products/handhelds/) and cannot find any of them that will monitor car sensors. Is this an international Palm unit they don't sell in the US?

The local mini service guy in town says that the temp " gauge " actually only has 3 possitions. Cold , ok, and way too hot. I is not much more than a idiot light which is why I went to a autometer temp gauge to get the true story.

there are lots, but they aren't sold by palm.... What you just did is equivalent of looking at the Intel site for inforamtion on Quicken....

Matt

ps search here, there are threads on it.

 

Can I Google it on Yahoo?

 

but it will work better if you google it on google! Try Auterra, Autoenginuity, AutoLogic and there are lots of others. There's a cheap one called Lap Logger as well.... Nology makes one, lots of people do. You can get it on eBay as well...

Matt

 

Cool Thanks!

 

Can you clear alarms with the palm software?

 

even the inexpesnive Lap Logger!

I have the nology pda dyno. It works well except that it is a pain to transfer the data to pc for printing and manipulation. Now they have and update to connect to a laptop. I will get this soon so that I can waste even more time analizing data and have pretty print outs to prove how nerdy I can get.

I did get the p0128 code the other day, It was 40*f out. The next day it was 45*f and no code.

I did go to the drags yesterday and put in a few gallons of 100. I drove around for a while,but unlike usual there was no noticeable power increase. Infact the car felt a little sluggish. I'm back on 91 and I have to say it feels better. Maybe too cold out? The lower coolant temps seem to be making a difference.

 

have said around 95 is the best.... But who knows! I guess you just have to try a bit.

Matt

 

Yeah, it was a bit of a suprise. I haven't had any pinging, but I can hear an oscillating intake note that corresponds to dips in the timing. I think this will even out over time. If not I'll see if mth can make a map that will be more consistant. I still have to see what's going to happen this summer.

I don't know which mod is the most beneficial, the missing pre cat or the t-stat. Either way, it has never felt better.
