Title: 1,9TDI ALH-help me please Post by: eazydaz on August 21, 2012, 01:55:14 PM I tune my Leon 1,9tdi ALH 66kw...I have nozzles powerplus764(0.226) and intake into turbo from ARL(airbox,maf housing,aluminium pipe)..Car is smoke and much eat :)
I rewrite smoke limiter with axis from ARL into my file-car is running better,but it still smoke, boost is 1,25bar.. What I have yet to try? Title: Re: 1,9TDI ALH-help me please Post by: chiptuners on August 22, 2012, 06:38:20 AM change pump voltage map to less volts, you can also change dw axis and begin of injection, log it also,

You have to recalibrate the MAF-linearization or switch to MAP-based smoke limiter. When switching to MAP-based smoke limiter you also have to enable EGR because of incorrect MAF-reading (should not be a great problem). The next thing is to recalibrate the pump voltage map + SOI maps and also to extend the IQ axis - otherwise you will never get it running properly.

SOI and MAF linearization what address have? Title: Re: 1,9TDI ALH-help me please Post by: tdifan86 on August 22, 2012, 11:29:22 PM Quote how I swith to map-based smoke limiter? You have to change some values in the hexdump and to "adapt" at least the "MAP vs IQ" - smoke map. You can use old 1,9TDI VP37 damos - everything is in there ;). If you want to do it oem-like, you also have to adapt a second map - "IAT vs MAP" - correction map. The more IAT, the less airmass is sucked at same manifold pressure => at higher IAT your car will smoke. Quote SOI and MAF linearization what address have? Post your ori-file Regards Title: Re: 1,9TDI ALH-help me please Post by: eazydaz on August 23, 2012, 12:48:18 AM I'll try to find something on the switch Map-based smoke limiter,I hope that I find something about it,because I´ve done it before.
When I use the VP37 damos,so all maps are crazy :( I attached the ori file Title: Re: 1,9TDI ALH-help me please Post by: eazydaz on August 27, 2012, 03:24:08 PM please,SOI and MAF linearization what address have?
