Std Injectors Over 240 Rwkw

[aps]

Well I would like to see all of the tuning data, air fuel ratio, boost pressure, and injector duty cycle before making any comment, I would also want to see 3 dyno runs at 30 second intervals, then you will see the REAL STORY in terms of power output.

Sorry if I'm stepping on your toes buddy (being a newby and all) but you've allready made comments on this particular dyno run - why hold back now?

<{POST_SNAPBACK}>

I believe these figures relate to a different car/engine and dyno test, hence why I said I would like to see all of the data pertaining to the car in question.

OK, time for some feedback on the DD dyno power runs today.

As the attached dyno sheets indicate, the car ran 255RWKW on the 10PSI map, and 234RWKW on the 8PSI map.  The runs were done on a hot day (IT 40) and, from what I can see, the AFR's are good.

<{POST_SNAPBACK}>

Now this is all starting to make sense to me and I can see why the power figures are higher than expected. Looking at the dyno graph I see:

1) Ambient temperature is at 25C and the air inlet temperature is 40C. This will cause the dyno dynamics software to build in a compensation factor and you then end up with an artificially high power figure.

2) The air fuel ratio is running leaner than ideal for a turbo engine keeping in mind long term engine durability. The air fuel ratio should not exceed 12:1/0.82 lambda particularly in the higher rpm range.

Food for thought and I'm in no way putting down the edit product rather just trying to make sense of the power figures posted and discussing what air fuel ratio is considered safe for a turbocharged XR6T engine.

Interesting. The dyno sheet for my run reads:

BP:100.5 RH:25 AT:35 IT:35 RR:015 TN:5.002 CK:950

Car pulled 260.7rwkw

Doesn't look like there was any temperature correction there as the IT and AT were the same. That day the temp peaked at 38 deg C.

I wonder how much compensation the dyno made there.

I would really like to see a response from Peter with that question.

Wouldn't a car with the standard intercooler have touble keeping the air temps down after a few consecutive runs? That wouldn't give a clear result.

Peter,

With the number of customers (and happy ones at that ) you have, the database of Dyno graphs must be huge.

Now that we have shown ours. How about you show us yours.

Could you please post a couple of dyno charts on a Unichip only tuned car, before and after install of the chip and tune. Would be nice to see the power, AFR and boost as well.

Would be great if this could be a customer's car, rather than an R & D run. A car belonging to a member of this forum would be even better.

Oh, and preferably not one that was run at 10 degrees in the middle of winter.

Thanks

Why Peter why?

It's almost common knowledge that the stock intercooler running 10psi is at it's limits, and running 3 consective runs 30 seconds apart will result in higher IAT's resulting in lower power readings. I'm not sure of the effects of the higher IAT's on the AFR's, but I'm sure Street Tuner can chime in and explain it.

I'd be quite happy to run 3 consecutive runs, but with the stock intercooler, I would prefer at least 5 minutes to allow the stock intercooler to cool, then repeat the test.

As I have mentioned before, the initial tuning caused the AFR's to lean off over 5k rpm with 10 psi, so to compensate the boost was dropped from 10psi at 5k to 8psi over 5k.

That's the beauty of the SCT tuning product, being able to adjust so many parameters.

Let's not start to worry about injector duty cycles at this stage. I've yet to see one of your setup's getting anywhere near the power levels of the 'edited' cars. To date, all I've seen from data you've shown is your cars running out of fuel and leaning out well below 200rwkw.

Is than an indictment of your products or a limitation of the Unichip piggyback system?

Peter,

I take it by the lack of reply to this that you haven't been back to the workshop as yet.

Do you think you could post some up on Monday?

[Pretzel]

No he has been on, his just plain ignoring you!

Might have some thing to loose? (Credability?)

This thread is all about people disagreeing with who's is bigger mine or yours

Why cant we all just face it everyones car is great and everyone has there own tuners they use so lets all just get along.

I use a lot of different forums put this has to be the worst one where people sh*t on each other.

I bid you all good luck with quest I am out of here.

good luck mate... shame to lose members but that's just the way it is... it would be easier if we all just aknowledged each other achievements without knocking them who cares if they are better then yours and who cares if you doubt them.

anyway... good luck mate

I agree with you, but when people post data to inform the forum members it gets a bit old having it on constantly.

I figured that since Peter is so ready to pass judgement on our data, perhaps he should share some of his. Like for like, well almost. His is already custom tuned (which is the way to go with all these products) and so should show terrific gains, AFR's etc.

BTW, I was hoping that your avatar would work the same way here as on the other forum.
