Is that the standard map?

 

Yeah just editing them to say as you posted

Ah ok, didnt know you were still adding more, let me know when you are done and I'll delete the random posts :blush:

 

No probs, thats all for now. I will get some more posted up with spacer and panel filter fitted and after some tuning.

Tidied it up.

 

So are you going to be doing the mapping yourself or is this just for a before and after for taking it to someone else?

Mapping it myself. I have my first ROM to flash this morning after fitting a plenum spacer and dropping in a K&N.

You tweaking the maps yourself or e-tuning from the logs?

 

Any questions ask away , or mail me your logs and I do your maps at a very cheap price.

Very interesting, still thinking about going this route myself, not decided yet.

Are you running a wideband setup?

e-tuning :wacko: that sounds interesting... wonder if I should sell my haltech and let that go towards an FI setup instead... :disguise:

Hi Mark,

 

I'm editing the maps myself which seems to be producing good results. I could be tempted to have some of your maps for comparison to what I'm producing though.

 

Uprevs documentation isnt bad, but not great either - I wouldnt recommend the self tune route for those without some existing knowledge of what they are trying to achieve.

Using the standard wideband sensors on the car.

Fitted the plenum spacer and K&N earlier, car felt no quicker and logs show very little difference.

 

Spent a little time tuning, this time car does feel quicker.

 

Logged 30-80mph in 3rd gear.

Stock 8.66s

Plenum, K&N 8.47s

Tuned 7.88s

have you setup the stock wide bands to give the correct AFR then?

 

I presume your using performance logging then if you laying logs over each other?

 

If your running in 3rd gear removing the throttle limiter will make most of the increase peformance your finding , also you find the car will run richer once you get in bigger gears, you need to running in 4th gear at least to get a better ide aof AFR,s we find.

Yeah the sensor voltages have been calibrated to the afr in the logging software.

 

I haven't seen much difference using the uprev tuned throttle, I am still using it, but the logs showed WOT in all gears with the standard throttle settings anyway (Assuming I'm understanding it correctly)

 

Thanks for the tip on the afr in higher gears - I get to the redline in 1st -3rd quite often on the road, not so much in 4th or higher, I'll check it out.

Tuning is just a hobby, I guess Im trying not to let years at uni studying automotive engineering go completely to waste now I'm not in an engineering role, albeit this is just playing with pretty simple stuff.
