I had my first one for about 600 miles before it went south (it's the control unit that dies). RMA'd it and got it replaced for free and I've had the second one for over a year now with no problems. Seems to be a random occurance that usually is fine if you just send it back (did a lot of reading on their forums).

Anyone who wants to get one just make sure you buy it from Innovate directly just in case you run into this problem also, and then it will be fine.

Great thread! This will come very useful to me when I start tuning the RT.

Stickyed the thread

this might be a weird question but on the fuel map we see threw tuner pro the TP value tops out at 67 but you got a value of 90 from the data log. does this mean that the car actually goes a lot higher than the ecu can read? when setting up the Afr changes your chart is going to be off due to the TP columns not lining up with the ecu TP columns did you take this into perspective? i don't know if i am wrong in this but i would be trying to setup the lw chart to look more like my ecu map with the rpm scale being set to the 800-6800 range and the tp scale from 0-67 data log it that way then change those to see how my overall Afr changed for the whole range. i think if you do it the way you have posted you will be editing some boxes when you want to edit others but this is just theory.

The map I posted is just an example, my actual map goes up to 90, and either if my map was like that, there is no way to edit a wrong TP column. You should not tune based on column order, you should see the TP value on top of the column on the LogWorks chart so you know which TP column you have to tune on the Tuner Pro map.

at the moment i cant get the info from calums guages to sync with my logworks. but none the less really good info

Thank you very much for this thread. I haven't read all of it, but it was exactly what we needed around here.

No problem man, everything is on the forums (everything but the Logworks specific stuff) but I just wanted to compile all information to make it easier for others.

Little update, I just ordered this and it is on the way right now:

so...according to my calculations. As far as finding k values for injectors. 1cc=50.10843373. I got this off of another thread by taking their examples of 683cc injectors with a decimal k value of 30182 and 600cc injectors with a decimal k value of 34341. That's a difference of 83cc's and 4159 decimal k value. So, to find out what 1cc equals I can simply divide 4159 decimal k value by 83cc's, giving me 50.10843373. Now, I'm trying to find the k value for 520cc injectors...I know that 600cc injectors have a decimal k value of 34341 so to stay in the same ballpark I'm trying to find what the k value for 80cc's is. so (50.10843373)(80)=4008.674698. So, I can take the 4008.674698 and ADD it to the k value of the 600cc injectors which is...34341, and come up with 38350 decimal k value. Now, I obviously missed something here because if it is true that 1cc=50.10843373 then I could multiply 50.10843373 by my injector size and have the right k value, but (50.10843373)(520)=26056.38554 On the other hand the decimal k value decreases as the injector size increases. Now, just because i'm on a roll here I was curious exactly what size injectors would have a decimal k value of zero. So I took the original 30182 k value from the 683cc injectors and divided the difference of 4159 k value between the 600cc and 683cc injectors into it. (30182)/(4159)=7.257032941 Now i can take this amount and multiply it by 683cc and come up with 4957cc, those would be some big injectors!

Is there any truth to any of this??

Not sure if you have seen this, but this may help you get started.
