Default Wish list for next UTEC rev...

TXS and all -

Consider this "user feedback". Here's what we (well, I) would love to have in rev 4.3 or 5.0 (or would that be UTEC 2005(tm)?):


1. Integration with Tuner WB for targetted AFRs.

2. Ramp function for ECU-to-UTEC and UTEC-to-ECU timing changes.

3. MAP-based option.

4. Pulse time adjustments for non-stock based injectors.

5. Per injector global correction - dial in an extra 2% in 1 cyl, or something.

6. OBD-II monitoring and DTC reading/clearing.

7. Selective CEL pass-thru - enable a map of CELs that you do/don't want to trigger the CEL light. Would clearly require #6...

There are other things that would be nice, like low-impedence injector capability, but those might require a hardware change.

Yeah, I know, I'm demanding. These are just what came to mind.

-Sean

I like the list. I would like it in this order:

2 (timing & fuel)
1
6
<-- ability to reorder logging columns. This would probably cause confusion on this board when posting logs. But sometimes I don't really want to see everyting in log 1 and the other logs don't have what I'm looking for.
5

The next five are things that I probably will never use but the rest of the community would probably like.

<-- AVCS control. This one might be one that I would move up on the list if I were to have/gain a better understanding on what it does for performance. Haven't really looked into it because I can't control it. Even if I could, could I do better than the factory ECU? It still might be fun to play with down the road.
<-- Rev limit remove for STi. This would be nice for those going to V7/V8/custom heads.
7
4 This one I might use.
3

Any idea when they may release another update? I'd love to see targetted AFRs.

considering the crossover hesitation is the most often cited complaint regarding the utec vs. other management solutions, i think it would be in txs' best interests to address that issue posthaste.

Specifying MAFS voltage to the thousandths place would make me happy

Macabre, do you mean displaying it to the 1/1000 place? All we do now it apply a percentage mod to the real MAF value. By definition, it's already at the 1000's place to voltage, because we can do xx.x percent (1/100).

Anyway, measurements are pretty much useless beyond 3 significant figures. While there is a huge difference between 4.5 and 4.6, there isn't that large of a difference between 4.54 and 4.55. I could, therefore, live with 100's.

About #2 - good tuning will take care of the fuel and prevent any fuel-related hesitation at all. If fuel changes even 4-5%, you're not going to feel it, and if it's changing more than that, you've done a lousy job tuning it. However, you can feel even 1 degree of sudden timing change if you're looking for it, and the conditions are right, and you can feel 3 degrees easily.

I didn't mention AVCS control because, honestly, it's below the bottom of my list. My RA ECU does a pretty good job with AVCS now. In addition, that's not something I really want the UTEC messing with - instantaneous 5 degree cam transitions could be nasty.

The most important feature we need is more range on the Injector scaling for OLF mode.. This 600CC limit is really hurting alot of people.....

The second most important thing is the injector dead time adjustment for the Utec. There are lots of injector options out there now and with the Utec you are stuck at stock injector timing.. It would be nice to not have to tune aroud this.

600 cc limit on the "stock" injector size.

You can say you are running 1000cc, but you have to tell the UTEC what the ECU thinks it has. Anyone who has reflashed their ECU to run larger injectors has to make an unusual map to deal with that situation.

Oopsie. I meant hundredths

I really want to be able to use this value to divine g/s reasonably accurately, or get some idea of how much flow difference I see vs. the same 4.5ish no matter what. 10ths is fairly useless especially near the upper limits of the non-linear curve where .1v is a very significant flow difference.

We are always listening to your ideas and feedback.

UTEC software is constantly being developed and I always review this and other forums for changes and features that we can add to the software.

Some of the suggestions from this and other forums are already being worked on.

I am a bit surprised that the injector range is not wide enough for some people, particularly the stock injector range. Some additional detail about how you are using this parameter would be useful.

That reminds me of the biggest request I'd have- an additional duty cycle map for the spare solenoid

4.2c has this fix already. The max value on both parameters is now 1000cc.

Since not everyone who can tune this has the time, or skills to get the transitions setup right. Some form of interpolation delay type algorithm for entering and exiting open loop. On both timing and fueling values.

Open loop IAT temperature and possibly barometric pressure compensation. I've seen quite a few instances of AFR's drifting lean as barometric pressure increases. Sometimes as far as .2-.4 AFR's.

EDIT: let me add to this... on time compensations for larger injectors.

I though you knew, for some reason. I will now proceed to hit myself in the head with a hammer. Try it, it's fun!

Per cylinder EGT probes. If one cylinder is a little hotter, give it some extra gas. If one is a little cooler, pull some out.

It's not the most important thing, clearly, just a value-added option. Hence the low place on my list, in fact, it probably should be lower.

Nice! I had no idea it was there.. I will load it into my utec and attempt OLF again...

- Interpolation across rows for timing and fuel. It already does this within columns.
- Temperature correction TABLES for boost, fuel, and timing?
- Boost table values that mean something (an actual target number in psi, bar, MPa, whatever)
- gear or speed-dependant boost control?

Change boost map from TPS to MAP for use as a water injection map.

Temp corection that will do + and - at the same time. Right now you can only use either + or - corection.
