Default water injection and cobb stage 2 HWG map feels good !!

hey turbo boys..

i just finished installing my water injection kit (single deluxe) from cooling mist.com (wheeeesshhh) 4-5 hour install. just this past wednesday.. because i am weak with electrical stuff, and ate dinner in between...

but back to the post..

i have a cobb accessport and i was running just the stage 2 map...

now that i have the water injection..set at boost @ 7 psi to come on, and running the 2.3 gallon per hour nozzle.

i have experimented with all the COBB OFF THE SHELF MAPS..

i have noticed the car feeling very strong with the STAGE 2 HWG AND only this map..

does anybody know why it is? Or any theories?

Any ways.. it does feel good, and I will continue to monitor the car in all different weather conditions.. hot and dry, hot and humid and the sorts.. but right now it is nice to have this response from the car..

and later i will have it tuned by riftswrx with his PRO TUNER package... but untill then, stage 2 hwg..

still want to know why the HWG feels so good?

I believe the HWG maps have revised wastegate duty cycles, to help boost a little more. THe map was originally desinged to help people that were not hitting target boost.

What does the 'H' stand for in 'HWG'? (Since we know the WG is wastegate.)

HWG = High Wastegate. Refers to the duty cycle of the wastegate. Some cars need more help getting the turbo to hit target boost, so the weastegate needs to be closed a bit more than on other cars. Sadly, you just don't program boost targets and have the car hit them. It's more complicated than that.

phamster - what is the peak boost you are hitting in 3rd gear?

i am getting like just 16.2 peak... with the HWG map and then switched over to the regular stage 2 93 1.22v and got in 3rd gear 15.9 peak, and then on the second pull on third gear 16.0 so about the same..

but again the HWG map feels stronger.. butt dyno readings.. but very calibrated.. though.. he he he..

anyways.. i saw your have the street tuner.. very nice.. is true: only street tuner users can make maps and share with only STREET TUNER's? or can you make maps and post for other cobb accessport users to use?

next question, do you feel you can make a better map using street tuner vs. just the stage 2 map from accessport?

let me know how you are doing with the street tuner... i am intrigue.. because i was once thinking of getting the street tuner myself but didnt want to F things up with my daily driver..

ok.. so HWG map is peaking just around 16.2.. and the other reg stage 2 is still around 16 psi too.. (my car never had problems hitting target boost of 15.8 +-.5, but just trying different maps for the fun with water injection and wham.. the HWG feels the best..) wish jorge of projectwrx gets his protuner soon..

Sounds like your boost targets are good. Higher wastegate duty cycle will also help you spool up faster, so that is probably the reason the car feels better with the HWG map. As long as you aren't spiking, sounds like you are golden.

StreetTuner custom maps can only be used by other people with StreetTuners. So, unfortunately you can't share with AP users. I think there is still power left on the table with any off the shelf map. I don't think anyone would argue with that. The question is just how much is left- that varies from car to car. Things like driveability are where I see the real benefit. You can spool the turbo faster, for example, and get more lowend grunt.

I think this holds for most setups wrt the ST. I've been told that for most setups (VF-series, TD04, TD05), what the ST gives access to is fine. For more 'exotic' setups, EcuTek may offer some more maps that would be helpful. I like being able to tinker with things, so end-user tuneability is most important to me.

Getting boost just right is the hardest part with ST. I think once more people start using it (and the EcuTek end-user tuneable solution), more information will be available to people and everyone will learn more. Right now, finding specifics is still hard. Timing and fueling doesn't seem to be too difficult- I still don't have a WB02, so I've only played around with getting boost correct right now. Of course, my boost gauge died a few weeks ago, so I had some downtime while waiting for a replacement.

Good thing Rifts has, or is going to get the Street Tuner PRO which will allow him to tune any ap car.
