maybe boost and timing vs a IAT sensor we can spray meth on to and get more boost or timing until it see's higher iat's just something to throw out there for the guys running methanol i remember doing this with the gto but was only added timing

 

this would be awesome!

 

you have any track times or dyno charts for that 256 setup ?

 

the gm sensor or the virtual tables from the flex fuel cars/trucks?

 

I'd like it to come with a Chis Miller video on how to cut 1.7' 60s all day long. Maybe I can improve on my 2.4s lol.

 

I have most of the cars ive tuned set up like this already. Its simple. Just move the iat2 sensor wire from the lower map to the upper map on the manifold. On my set up when my IAC kicks on the E85 drops iat temps a good 20* so its simple to tune for.

This could be improved by implenting a multipler table off of the new AIC table that is active only when the IAC/meth is spraying. Which leads to another table that would be nice and simple.

The extra gm solenoid on the manifold that controls the BOV has some potential. I have used it as a nitrous solenoid controller based on boost but it is limited. We need to expand the bov solenoid controll table to a larger 3d table then give it a multiplier table for spark. This would be a perfect meth/nitrous/AIC/ or anything you want triggered based on boost. If whoever is designing the OS could verify that the address look up is to the manifold MAP PID that would be amazing. You could even use it as a secondary ebc so we could max torque to gear tables and allow true wot in first gear. Would make launching much smoother. This would be a true boost by gear set up. Not a "torque/load" by gear.

A DAL by gear.

Maybe wastegate DC by gear.

A engine run time after ignition is turned off table would be nice. Basically a "turbo timer".

Like already stated switchable map set up. Wether it be cruiz control, traction control, or a switched power input . Lol starting to sound like "Tephra". Possibly we could get some help from him? He has done wonders for the evo community.

Alternate injector constant table for E to 93 switching.

I know all these wont work but it gets your head thinking. Sure yall can branch off one of those ideas to make it better.

 

I knew Taylor would eventually chime in on this!

 

With all the above suggestions, can you include "stand-alone" capability so the LNF ecm can run without the BCM etc. For all our LNF swappers...
(Like Trifecta offers.)

 

but yeah, anti lag would be so wicked haha

 

Cobe just volunteered himself to do all of the programming/tuning involved with the anti-lag.

 

a lot of work just to sit at drive around and listen to booms and cracks to impress other people. that would be the main reason a lot of people would want it.

 

Yeah, we thought about it and decided we probably won't add als. I use it at the track, but not many people will, and most people using it would be doing more harm than good.

 

An overboost protection would be nice. Like cut all ignition if say a boost line popped off or say there was a random significant spike. I don't see any harm in that since it technically wouldn't be a misfire but just killing the engine all together. The bad thing is it would be hard to read with 3 bar map sensors but 4 bar map sensor support and maybe a kit could be achievable and wouldn't cost much to make. Your profit would probably be significant if there becomes a low compression piston set available for the lnf. I know GM makes a 4 bar map sensor. Not really a Tmap but people with blow through maf setups which are pretty well the norm now will be reading the temperature there so I see no reason why the LNF even needs a Tmap after changing to a blow through maf setup.

 

 

really?!?!
you can do this **** yourself with hpt as it sits.

 

Please share your advanced knowledge with me Sensei. I clearly don't have your expertise on the HPTuner product.

You might want to ask about interest with this on the Kappa forums also.

If I remember correctly on the Kappa platform the pin the Colbalts and HHRs use for the electric power steering is free. I looked into integrating my PLCs many functions (7X9) with this single pin, what I would have to do is set function and command to be triggered and controlled by variable voltage, current, and/or impedance or a combination of them with in "range groups". All the data I found showed that the Bosch ECU could do everything I wanted, but configuring it was a roadblock.... then I got sidetracked on a different project and didn't follow up.

Maybe there is a sacrificial pin on the Colbalt HHR plate form that could do the same. Then use a PLC to control whatever external functions you want like NO2, Meth, Cutouts, Secondary Injectors, Variable Suspension Settings, Smoke Screens and/or Ejection Seats.

e85 mod pl0x, should be #1 on the list

 

I think something to the tune(ha see what I did there) of an ECM being able to hold multiple tunes would be a feature that everyone could benefit. Going from a E85, to E47 to 93 or 91(for trips) on the fly with the easy of hitting a button would be amazing and sure as hell a reason for me to buy such an inovative product. Just add more non-volatile banks of memory. What do you think Matt? I know it's just a convenience feature compared to the cool idea's from others but something to think about.

 

if they can use the flex fuel tables from the flex fuel cars no button needed. computah will adjust accordingly

 

I just looked through my documentation, some says the ECU is capable of 5 "power modes", this may be my miss reading of German, but the ECU was designed to allow at least 3 different "power modes". This doesn't mean completely different tunes, what it means is some tables (injection, timing, ect) can be selectable "on the fly". Completely different tunes maybe possible but would require a power cycle of the ECU.

The ECUs on board memory is not feasibly upgradeable, however it is large enough that 3 different modes looks to be no problem. The stock tune leaves nearly 62% memory available.

An addition that would open up possibilities for all sorts of crazy fun would be the ability to interface with the CAN bus to use that as additional digital/analogue input/outputs. This may also open up some control or at least interface with the BCM and TCM.

Yes and apply the button pressing used in Trifecta tunes. Could be killer. But I'm not sure how it would work with things like e85. I'm not sure your main tune could be 93 and your alternates be e85. Would be hard to start. etc

 

Nah no times with it yet still on the stock trans and am scared to break another one just roll races for now

 

you have control over the cams. change the LSA.

 

Hi/low boost setting using say the cruise control button. Kinda like what u have on the zfr car except ecu controlled. I remember Matt or someone saying that the factory solenoids made it hit or miss on accurately being able to control boost vs rpms when we start getting into higher boost.

And having e85 composition and associated on the fly timing/boost/injection adjustments via virtual or flex fuel composition sensor would be choice
