I was wondering if we could get an update on when turboxs will be releasing their staged maps. I know they advertise having staged upgrades and UTEC maps to match each stage. When can we expect the next stage(s)? any idea? I can't wait.

 

I agree! Perhaps Turbo XS can comment on this. I bet Malibu Jack comes up with a stage 2 map first!

 

I have a bunch of stuff on my plate, but we are going to be working very extensively on the new firmware and new maps over the next few weeks. I haven't really released any new maps because I know how huge of an improvement the new firmware will be and it has some features that I really want to make use of in the new base maps.

So the answer is "soon" for now.

Honestly I've been holding off on building any new maps until the new firmware.. I can't really screw around with my car with the stock injectors, so I want to install the new injectors and pump before I do more.. I get TONS of wheelspin (in third gear) when doing my "Tuning runs" at this point, so its hard to get consistent tuning info.. All I'm doing is running 22psi of boost (approx) with NO TIMING MODIFICATIONS from the stock ECU, and only very mild mods to the fuel map (to add fuel to compensate for the Buschur filter)

I also have a very interesting new toy showing up on monday.. an Ultimate Racing Blow-Through MAS Sensor conversion kit (removes the troublesome MAF sensor) I'm going to put it in my Buschur upper intercooler pipe. (Cut a section of the pipe and flare it out I suppose)

 

Is this just a different MAF sensor, or does it truly get rid of the MAF sensor to allow use of a MAP sensor? Other than allowing use of a better intake, what advantages do you foresee?

 

Please put up a post on your UR mas sensor and let us know if you like, I've been considering this but haven't heard any thing +or-,

 

Hey Wildcat,

Found a link on URs website for the MAS sensor, Looks interesting and will help with tuning with aftermarket intakes but at $650 I'd like to see some solid dyno feedback

Although this thread wen't a bit offtopic.. I personally feel that the UR Blowthrough MAS has quite a few features that make it a great alternative to a speed density setup, and a great addition to the UTEC..

I have not recieved the sensor yet, it will show up on monday. However you have several choices for mounting, it can be mounted in the upper intercooler pipe, or in place of the stock MAF sensor. It is *NOT* sensitive to air turbulence like the Karmann sensor might be, therefore MAF misreads are virtually eliminated. If you place it in the Upper intercooler pipe close to the intake manifold, you can run a BOV and not have drivability issues.

Speed Density conversions have always been something I was cautious about, in the past, a MAS sensor system was preferred OVER the speed density setups on the older cars I used to work with. a MAS sensor reads true air volume regardless of density or temp, a speed density system relies on calculations for temp and manifold pressure to give air density, however that calculation is not always totally correct and under engine vacuum, has potential closed-loop drivability issues. The MAS sensor conversion calculates the air passing through the sensor, so the output of the sensor should closely mirror what the stock MAF sensor would have while allowing more air volume and ignoring turbulence.

I was told the sensor is not a GM Hot wire sensor, but is a Hot Wire sensor.. these sensors have the ability to calculate the flow rate based how much power it takes to maintain a "Hot Wire" at a particular temperature, density and temp can easily be accomodated since colder temps and more dense air, removes more heat from the wire.. same with more air.. so the output will always correctly compensate for the volume of air passing through the sensor.

Hopefully I'll get the sensor installed quickly (I have to see the kit to see what mods need to be made to accomodate it) and give some input and recommend some adjustments to the UTEC to make the best use of it.

In the end, it eliminates one of the three remaining restrictions I feel exist in my setup.. the MAF sensor, the remaining two are the Throttle Body and Intake Manifold (Both of which will be addressed some time in the future, maybe someone can help me out on those since I'm running out of hardware money.. LOL)

 

keep me updated. If it works, ill get one and be done with this intake hassle once and for all!!!

 

Ok.. It showed up today.. I'm not sure of the diameter looks like 3" since its the same as the Buschur Intake pipe.. But with a coupler and filter, it looks like an easy fit.. the wiring itself is easy too.. I'll post a few pics on wed after I get a filter and coupler for my intake pipe. Anyone know the diameter of the stock MAF sensor?

 

definitely post pics and your opinions. This might have to be my next mod. Sorry I don't have an answer to your question.
