The sender is dead on the money at 17.5 gallons displayed on the Quad at 1/2 tank. I've been below 1/8 tank few times and Quad gallon display has right there within +/- 0.05 gallons typically.

Another way to look at it. Here is the stock 30-inch tires sizes and dimensions. Here is the stock 31-inch tire sizes and dimensions. Then the popular 285...

RV275 injectors. You need to look at the timing setting you over advanced. That is the only reason it popping and backfiring. I would start out with 15, 18, 21, 24 with a Max of 25. Then on the Low PSI Timing Reduct set it for 5 and then 50% scaling. Be a good start. You need a good amount of retard on sudden WOT operation. That is why the backfire or bucking. Like my truck even with 7 x 0.010 injectors, I can reach over 28* without backfiring or bucking. Retarding timing will build boost rapidly by dumping more expanding gases out the exhaust manifold to the turbo. Once the turbo lights off then the Quadzilla can advance the timing and pour the fuel too it.

Ah... I was hoping there was an update. Thanks, I'll give that a try tomorrow. I assume its this update then... Opps, that's a 2.8.4... @Quadzilla Power you need to upload the 2.8.5 here on M73M.com...

As for the flooding it pretty well over. Things are drying up for now. As for the MPG game. 20.64 MPG on the last tank. I was hoping for much more being I past 300 miles at the 5/8 mark on the fuel gauge.

Somedays I wish I never sold my 1973 Dodge Charger...

The way I look at Smarty S-03. No matter how much you can adjust the Smarty S-03 you still have to play by the rules of the ECM. It is like having an Edge Comp or Edge Juice (no wiretap) that is stuck on Level 1 but sublevels you can adjust. Remember CANBus fueling is from 0 to 4095. That is it. There is no magic bullet than the Smarty S-03 can do to expand past that fuel limit. Timing wise yeah you can adjust it but no one really knows what the map looks like. Is it optimal for larger injectors, not really? The only thing a Smarty S-03 does is get to the 4095 faster than stock. Torque Management allows for fuel early heading to 4095.

Stock sizes... 265/75 R16 245/75 R16 (door sticker) 235/85 R16 One ton 215/85 R16 One ton

35 inch tires and 3.55 gears is a bad combo. Always high in EGTs. I'm down to 550 at 65 MPH now but 30 inch tires and 3.55 gears.

Give up. You'll never finish that list. I'm still fixing crap and adding back to the list.

I'm curious if there is a update of firmware for the Quadzilla. I've lost count of what version I've got and what is the current version. I've got fueling issue in the 1000 to 1200 RPM range. For some reason Quadzilla oscillates up and down regardless of timing. You can watch engine load jumping up and down.

I should con you into writing an article on this for others. I'm sure others would jump on it.

He got away for cheap. I was right at $2,000 with the ARP studs, machine shop (valve guides and seals), then gaskets and so forth.

Wow. Talk about a time long forgotten. Back when pedal cars are made of steel. Woman (or girls) wore dresses. I wish I could turn back the clock some times.

Makes me want to pull my cover again and check my bolts. Might explain the weep oil leak behind the case.

Got them installed. I used every single blub. All 20 got used. I'm doing a full run test. I've got all the light on while I'm here at the RV and test to see any get hot. Here you go...

Size is only half of it. Weight is the other part. 285's typically are close to 90 to 100 pounds a tire with the wheel. The rotational mass has a minus in there too. This why ricers beat us hands down. Small tires and little rotational mass.

Me I opted for the tip to keep the soot off the truck. 5 inch tip is what a friend gave me.

My current tune looks to be able to reach nearly 22 MPG then still on the 245's. If I can do it twice ill release the tune for download. Find out more when I fill with fuel today.

Quadzilla runs off of Circumference measurement rather than rev/mile or tire height. If you want to just pass the stock speed signal without math enter 95.7 that is the pass through number.

White smoke... Timing retarded excessive blowby worn piston rings pop pressure too low on the injectors valve lash incorrect Basically white smoke is unburnt fuel that didn't ignite. Being that compression creates the heat to vaporize the fuel to make it go bang. Now that makes you think of all the things that might affect compression or fuel atomization. Finer the automation of the fuel the easier it is to ignite.

I don't care who you are that is a killer looking truck even with the tip. don't feel bad I've got a 5-inch tip hanging out that side too.

Gotta ask did you tighten the injectors hold down first or the cross over tubes first?

99.4 inches... Circumference...
