So the ecm sends a fueling and timing command to the vp44. The vp44 then does what it can and sends a response back to the ecm stating " I did this timing and this fueling" If the timing command sent does not match the timing command actually done then you get a p0216 code. I would wager a bet that your pump has been on the way out for awhile now. p0216 can't be related to an injector issue as far as I know.

I have siliconintake stuff on my truck. seems to work good.

No kididng. Now I have 7 days to get the trailer appraised before the temp tags expire. So far the closest place I know of to do so is ~1 hour away up the pass. I have 2 more places to call locally to see if they can do it.

Anyone else see the iriony of where I am having to send all these documents to get this thing registered? Yep the Department of Revenue.... ugh good news is the certified Vin inspection with the Colorado Highway patrol went fine. They signed off on everything and gave me more documents, thankfully they did warn me to fill out a few documents the DMV did not tell me about. I asked about the homebuilt thing and they said they would not have allowed it given the documents and the various welded on tags etc. Oh well 3 steps closer. Now I just have to get it appraised and get a surety bond on it, then wait for the documents to come back from the state.

Does anyone want the spot that I reserved?

And it depends greatly on the tuning in place. My truck would fail smog if I just ran stock tuning and my 7 x .009's My altitude make my truck pretty smokey on stock tuning. What does the test actually consist of?

I wouldn't worry about the elbow personally

The ECU itself will work just fine with the right flash. It will very likely work out of hte box if the truck is a true 00 with a cam and crank sensor. If does need a flash then bob at smarty can help flash it or the dealer can do it. I have the flash files as well, but no way to flash at this point.

4300k is supposed to be hte most visible light possible, but anywhere in that 4-5k range works good.

I think 40 is roughly = 1 cm^2

Alright so there is a function wrote into the code under k_keeptime that is made to increase the vane position based on TPS related to boost. So you can see at %71 tps and above ( edit if you like) that I open up the vanes by 20 if above 20 psi and below 30. If you want to open more then adjust to be greater than 20 if TPS is = tps_high // TPS_range calc process if (timer % 200) { if (ThrottlePosition <= 20) {TPS_low = true;} else {TPS_low = false;} if (ThrottlePosition <= 45 && ThrottlePosition > 25) {TPS_midlow = true;} else {TPS_midlow = false;}// watches throttle input to increase or decrease vane position. Vane position mapping is based on low throttle input. if (ThrottlePosition <= 70 && ThrottlePosition > 45) {TPS_mid = true;} else {TPS_mid = false;} if (ThrottlePosition > 70) {TPS_high = true;} else {TPS_high = false;} if (TPS_low) {TPS_range = 0;} //supports low throttle cruise. if under %20 don't change vanes if (TPS_midlow){ //20<tps>45 if ( BoostPressure < 2) {TPS_range = -60;} else if ( BoostPressure < 5) {TPS_range = -40;} //it will try and spool the turbo if tps is 25><45 calc section "-" the tops_range so setting number here to - means housing size shrinks. else if ( BoostPressure < 10) {TPS_range = -20;} // 25<tps>45 and boost less than 10 half cm smaller else {TPS_range = 0;} //other wise leave vanes } if (TPS_mid){ //45<tps>70 if (BoostPressure < 50) {TPS_range = -30;} else if (BoostPressure < 10) {TPS_range = -20;} else if (BoostPressure < 20) {TPS_range = 0;} else {TPS_range = 20;} } if (TPS_high){ //70<tps>100 if (BoostPressure < 10) {TPS_range = -20;} else if (BoostPressure < 20) {TPS_range = 0;} else if (BoostPressure < 30) {TPS_range = 20;} else {TPS_range = 40;} } }

so the situtation is that you get on it WOT then DP spikes and you get choking in the turbo? Are you reading Throttle position?

take the fuel cap off and see what happens. Guessing your tank is not venting.

have you altered the base curve of the tuning? Just trying to make sure I know all the facts so we can get this sorted best.

Well that's my question why 30 psi drive pressure? Are you having issues with DP? What shaft speeds are you seeing? What ratio at that WOT? The turbo seems to sit in the sweet spot for me, but I think that has to do with me seeing the values for the shaft speed steps. IE at 100,000 rpm I am at ~12cm^2

The mini h1 kit runs $350 ish. Then housing and some sealant

Welcome to the club. We are all still learning what our trucks like. If you thought the default tune pulled hard wait until you get into the timing tuning. I recently found out my truck likes a lot more timing than I thought. Anyways I look forward to seeing where you go with it.

So you want the Vanes to try and keep DP at 30 psi max?

Where in the code are you putting it?

You might have to repin the plug but that's it.

Look at dap for the quad. And you want the iquad

Yep, welcome to the world of being able to see. the Ds2 is a great setup, bigger lens, better light, just more expensive compared to the mini h1's and harder to retrofit.

what profile are you using on the phone? make sure you are using hte 1998-2002 profile

alright, If you are having the shudder / rattle at sube 1200 rpm this should resolve for you. I wouldn't call it a true issue as it won't hurt anything, but I understand the oddity. This flash will disable light load timing until 1200 rpm is hit. adrv2XXXX.exe

I have not tried it on a new turbo personally, but I see no reason that they would change how the turbo talks. I believe someone over on lilbb.com has a newer vgt that they use. they might have insight.
