Quadzilla Adrenaline V2 Testing

[Mopar1973Man]

I would have to say your right the sensor is shot and failed within specs. It other words the MAP sensor reporting a valid number of boost but not out of range so it would never trip a code. Rare but it does happen. Your voltage appears correct for the sensor circuit.

I have been getting an overboost/turbo overspeed code every once in a while.  Wheres a good place to get a quality sensor?

[Mopar1973Man]

Any part store should work. Some will say go to Cummins. The problem is no matter what its about $100 to $120 sensor. They are not cheap.

My own sensor failed like this as well back when.  

 

I would pop the map part number into eBay and see if you can find a new old stock sensor.

[Mopar1973Man]

Watch out for Chinese knock offs that might be super cheap on Ebay or Amazon.

Just to be clear, the value shown on the iquad isn't atmospheric pressure being shown plus actual boost is it?  should that value read 0 at idle and if the engine is off but the key is on?

 

I have read a couple post where people were seeing the same values as me at idle and thought their MAP was bad but it turned out to be the value of atmospheric pressure being shown and not actual boost pressure.

[Me78569]

The Iquad screen will show between 0-2 psi at idle depending on the truck.   If it is showing 14 psi then your truck ecm is literally reporting it is seeing between 10 - 14 psi at idle.  

 

Atmospheric is considered in the calculation

[martinique78]

Ok, thanks...i just wanted to make sure the quad did the calculation.

Well, I guess I'll take a second shot at typing this, since for some reason it didn't send and 'poofed'. Must be Monday.

 

So, I haven't done a ton of tuning, but I made a little bit of progress with my plans of tuning timing on my truck. Even in the flattest part of Canada, its tough to do steady state tuning with minor changes in wind/grade... Especially since I still haven't been able to export my logs. What I really need is a dyno... But I'm too cheap, and especially can't justify the cost while I'm in experimentation mode. But, I digress...

 

Here's the issue I'm having: I need the Max timing limits increased, especially for 1500 and 2000 RPM, and possibly 2500, not there yet. Confused? Think I'm a meat head? Haha. Perfect! Let me explain.

 

So, if you recall, the goal for my timing tuning is to get a timing curve as efficient as possible using logged data from EGT's and canbus fuel levels. I want to use the Max load timing feature for this, and I'd like to avoid the cruise timing feature. I'd like my timing map to be dynamic enough without applying cruise timing. I really think this is doable and important. Load timing should help facilitate this. I decided I should switch directions a little and get a good starting point by comparing lvl 0 (stock) timing to lvl 3 (custom) timing. What I learned, is with load timing at 3*, or even 2*, I can't event reach stock timing advance cruising at 1500 RPM, with Max timing set to 18* (upper limit). I have a 3.54 rear and 35" tires, so this is important. My highway 100km/h cruising RPM is like 1650. Yes I know I can enable cruise timing, but I really think this would be a bandaid, and only help things at steady state cruise, no hills, no towing, etc. No good in my amature opinion.

 

With load timing set to 2*, and 1500 RPM timing maxed out at 18*, I'm still at least 1.5 * -  2* below stock advance at steady load, whereas I'd like to be more advanced because of my fuel setup. I have similar issues closer to 2000 RPM. I can only assume this is likely the case for many scenarios, and not just cruising. This kind of renders the load timing feature unusable for me, and I'm a sad panda at this point. @Me78569, tear my post apart! What do you think?

[jlbayes]

@Mopar1973Man has played the most with mileage and timing from what I have seen. Even in his case he was limiting timing due to seeing no gains having it far advanced.

[kzimmer]

I accidentally ran 23* today in a situation where lvl 0 wanted 18*. Saw an immediate drop in boost from around 12psi to around 8psi, with a noticable drop in both EGT's and canbus fuel. Not too bad of a rattle either. This leads me back to my previous assessment that my fuel setup is retarding final injection timing. So my timing numbers might be significantly higher than others with the same end result (peak combustion at 15* ATDC ideally)

First time in my life I am happy to see the emissions test notice in the mail.  

 

Time to give the state money.  I will be curious how much power I put down with my %100 clean tune.

[kzimmer]

Pull up to the test stand with 150% canbus and some wiretap, leave a cloud. And then set it to level 1. Lol.

Be careful with that... I've got a good contact with Ada County smog testing in Boise ID that I've been talking too. There is one customer that did something similar. He came in with the tuner at 50% and ran the test and passed the test. Then he cranked up the tuner and smoked out the tech.

I know I kid I kid. Hahaha that's hilarious though. I almost wish there were emissions tests where I live, just for the satisfaction of passing.

[Mopar1973Man]

In a way, I wish it was statewide (Idaho) for all the lame punk kids and their truck would have to clean their junk up and quit blowing large clouds of smoke. Down in Boise I run across Ford and Chevy constantly wanting to roll a big cloud on everyone. What's more, fun is whipping then from light to light and not making any smoke at all.

[stumblinhorse]

They just signed in a bill making "rolling coal" a primary offense here in Colorado.   So we will see where we end up with any amount of smoke.

"Welcome to Colorado, where we roll doobies, not coal".

[trreed]

That's basically true, @kzimmer.  

It's only a $100 fine, which I personally think is hilariously low for how much hype there was for this bill to pass

Question about the canbus fuel level (0-4095). Assuming no wiretap, is this number an absolute value of how much fuel is being commanded? Are there any other factors at play that dictate volume of fuel injected besides the canbus fuel message?

 

For example, if I'm driving at 100 km/h in 3rd gear, overdrive turned off, my commanded canbus fuel level might be 700. Let it shift into overdrive, and canbus fuel might jump to 850. EGT's might increase 150-250 degrees F as well. Logic tells me I'm using more fuel. Downshift and get the RPM's up over 2000 instead of 1650. 

 

Any other factors I'm missing? Does RPM play a roll?

 

Thank you,
