Today I went over to Speed INC. and Jim and I tuned a 3bar car on 11lbs of boost.

The tuning went very well. On 110 octane using an open loop tune and very large injectors we were able to get most of the tune done.

At a safe 11.5 air fuel ratio we were able to get 638rwhp out of the car. We were going to up the boost but ran out of time.. so expect more posts in the next few days..

We started the tune on the rich side to be safe and after a handful of passes we were able to iron out the VE table to achieve a flat 11.5 air fuel ratio across the board under load.

Just another product you can only get from HP Tuners.

ps. Don't bother reading the O2's.. 110 octane and stock O2 sensors do not mix very well.

 

 

i was just gonna say, "Show me the VE table." thanks.

...by the way. Been playing with my HP Tuners for the past few days. Love it.

 

WOW that is awesome Keith, want to fly out to here and tune a 16psi car
As for the end user, about how hard is this going to be to set up and work with for us FI guys? I already have my hands full so to speak with your awesome tool right now. Should I put off trying to tune my car any further until you release the 2-3 bar set up?
That VE table looks NICE

soooo will the 2-3bar upgrade be released real soon.....1.6 too...

We only tuned the VE table up to about 175 kPa (11psi).. and just added fuel at higher boost just in case the blowoff fails or the car somehow overboosts. The car will be tuned to much higher boost though.

It's really not that difficult to setup. Fit your 2/3bar map sensor to your intake. Unlpug the 1bar MAP and plug it into your new MAP. You may need an adapter plug for this. Unplug the MAF sensor and start tuning.

frcefed98, you should be able to start your tune without an actual 3bar in the car. You can tune up to 1bar levels to iron out your VE table. Then when you use our 3bar product you can copy over your VE table as a good base... Then just add fuel up top and lean it out until you find your happy place. You want to start tuning boost rich and take away fuel instead of starting lean and adding fuel.

It really helps to tune the car on a dyno. If you tune the car on the street with a wide band it would be good to have someone else drive the car while you tune. That way you can see how the car is reacting to more loads and tell your driver to back off it the car is thirsty for more fuel.

Yes, 2 and 3bar and 1.6 will be released very soon.

 

Cool thats want I needed to know It will be nice to lose the MAF. As for starting my tune, got a pretty decent tune already...was just trying to polish it up a lil more for opening day in Feb. need all the horsies I can get.
I try to tune on the street with my LM1 as much as possible, its cheaper...crappy part is I can't be the passenger I get freaked out when we got WOT and I'm on the pass side...but behind the wheel i'm fine
I'll get it though, just need to polish it up a tad, hope I can figure out the new map sensor feature without too much hassles.

Keep up the awesome work Keith and the rest of the HP tuners crew

I take it that is an open loop tune?

 

looks to be.

 

Yes, an open loop tune although it doesn't have to be.

This car uses an open loop tune because its run on mostly race gas.

So would you then sort out the base VE Map from 0-100kpa and then extrapolate the rest up to what is needed?

 

TTT for sscam68's question and I cannot believe that a lot more interest hasn't been shown from the rest of the FI gang here on LS1tech....especially with all the maxed MAFs out there.
J

 

I'm not FI...yet, but this **** intrests me. Maybe like to it in the FI section to get some more attention?

 

looks good, are there any direct replacment map sensors that will plug into a ls6 intake, or do you simply hook a vac line to one of the 2/3 bar units? Just curious as im installing a ls6 in a few weeks, and would wait until i could install a direct replacement one before installing the intake.

What kind of time frame for this to be released? Any expected cost? and will you support the 98 cars?

Thanks

Ryan

 

are you guys using the 89 turbo trans am 3bar map sensor?

i wonder how hard it would be to use the motorola mpx-4250ap series they are a bit cheaper but need to be soldered to a board. $25~ (2.5bar)

 

i hate it when i miss threads.

anyway how does it drive on part throttle?

cant wait till they release it
that is so

but why isnt the WB registering?

 

We have adapter harnesses to make the older style 3bar MAP's plug right into the factory harness.

 

Speed inc always comes through, looks like I'll be ordering up the harness...whats the PN or can I find it on the website?
J

 

Very nice, looks like this stuff is close to becoming plug and play.

 

<---dumb

I read too fast...so many posts, so little time.

You guys can totally stop teasing us and release the update already.
