your if your going to be unflashed you'll need the timing to regain some the torque lost on the low end. TTP however has a flashed tailored for this particular application.

 

I just prefer to have the ability to adjust timing myself. not knocking on the flash or anything, I am pretty sure it is flashed correctly but once you start adjusting fuel it is going to change timing because of its piggy back nature.

 

This is true, however the timing change when tuning is not extreme, and it changes in the proper direction.

For instance, if your tune is "too safe", you will lean it out a little which will increase timing a little.

If you are picking up some trace knock, you will richen the mixture some which also reduces your timing.

So it actually works pretty well.

Thanx for info

 

bump for updates

 

I have it partly done, but had some special stuff to finish for Scott (TTP).

Its getting there.

How is the new feature going to control timing, via crank sensor or what or the way utec does.

 

New version firmware is working great Bob. I have released it to a few customers already with success. Driven about 500 mi on it and have lots of logs. Good Work.

 

Paul and I are fine-tweaking some. I really like the way its driving.

Timing control is next as soon as I put the finishing touches on your stuff.

The Pro is capable of using either the coil outputs or the Crank/Cam sensors for timing control.

We will be starting with Crank/Cam sensor mode, and add the coil output mode later.

I have some boost control improvements in mind as well.....

We have a customer with a Lexus V8 powered Supra running a Pro and N2O. He is using the boost control output to control the N2O (triggering).

(I had to tell somebody....!)

That is good stuff. Man I have so many ideas for that unit that I don't even write them down anymore. You need like 6 more i/o's for all the things that could be done. The most recent idea is to allow the new boost enrichment settings for V4.5 firmware to be individually set up for both of the switchable maps. I like the boost enrichment fuel punch on pump gas alone, but I want that turned off on meth injection map. I know that will take you all of 20min to update, but thought I would share the finding. It runs a tad rich on peak boost with meth on the new firmware. FYI. Keep up the great work.

 

The latest change that Bob and I have been discussing will address that richness as you reach peak boost. I'm not sure if Bob is going to use only the existing settings to implement it or add a few more, but it should allow for more consistent A/F ratios during spool up.

Do you have any screenshots of the software

 

The software is the same as before, it just has some new settings that can be adjusted. There are a few screen shots here on the forum.

Alright Paul, you are the brainiac. Help me find out what AIT voltage reading would be considered, warmed up.

What I want to try to do is setup variables for cold start enrichment which will allow you to turn it on, but not activate unless the AIT sensor is indicating that the air is cold or the motor is cool.

We could run this off of coolant temp, but that would require another tap to the ECU and I think we are out of wires.

Let me know your findings!
