any luck phenix ?

still looking for a good scaling for pte 1000's i can email my buddy to get his car running right

 

Here is what I used on PTE 880s that I scaled yesterday:

Scaling 731

Latency

3.312
2.184
1.32
0.96
0.696
0.408
0.288

The car was an Evo 9 with all the bolt-ons and HKS cams. Trims maxed out at -4 for the mid and +2.6 for the low.

Treat them as a starting point only. I have noticed that PTE injectors are harder to scale than the Densos and RCs that I have scaled.

 

Starting point for RC 750s

Scaling:

636

Latency:

6.12
3.12
1.992
1.224
0.792
0.576
0.312

Evo 9 with TBE w/TP

 

tried these settings @ idle using mitsulogger
fuel trim low: -10
fuel trim mid: -4

still haven't had the time to go for a cruise. my mods are similar to the one you set these for just w/ a HFC and arc box. any input on this as far as getting the lows closer to zero?

 

This is my scaling with my PTE 1000cc's

Scaling: 725

Latency:

7v 9.4v 11.7v 14v 16.4v 18.6v

2.186 1.281 0.771 0.458 0.283 0.172

 

Try this

Scaling:

636

Latency:

6.12
3.12
1.992
1.124
0.692
0.476
0.212

I lowered the latency by 0.1 in the 11-18v slots. That should bring your low trim from -10 to zero.

 

Anybody here run FIC 1050/1150's or RC 1200's on stock ECU? I want to go big and never have to worry about tuning for the FP Green or E85 again But they also need to run halfway decent on 91 gas as well.

 

Working on it. For some reason my STFT Low is not changing as often as my Mid Trim. But its getting better. I have some other issues going on with the car that I working to get resolved.


Yeah but the nice thing about the Evo 9s are the Trims are reset after flash so changes occur much quicker than the Evo 8's, Thanks for the info though.

 

Hey NJ....these settings for the RC 1000cc are ON POINT! With the Scaling @ 835 my trims are at -1 Low and -1 Mid....good job mang!

 

Phew, just completed 29 pages worth of lesson. Could I use PTE680 scaling and latency with my Sard 700cc injector?

My current Mitsulogger showing
FTL FTM FTH
12 12 12
12 12 12
12 12 12

While Evoscan showing:
FTH FTM FTL
111.71875 100 100

Which one give more accurate reading?

 

SARD 700cc's are Denso 720cc injectors. (really flow more like 690-700cc) Which have the info posted in this thread somewhere.

 

After reading through all 29 pages and prinitng out settings for my model injectors (FIC 1000's) and getting totally frustrated by the fact that the scaling provided didnt work I finally started changing latency to get a smooth idle and ended up with RC1200 latency settings on the AEM chart. What was weird is the trims could be within + or - 3% range with posted settings but idle was rough. I thought injectors might be bad fouled plugs loose vacuum line etc. but they all checked out. besides the only thing that I changed was the injectors.

Is it safe to assume these injectors just flow a lot as the latency values have to be so high to get them to operate properly?

I am in regroup mode and will "attack" again tomorrow.

OH yeah they are scheduled to open an E85 station in the area can't wait and will spread news to the North San Diego peeps when/if this station is a reality.

 

A rough idle is usually due to running too lean at idle. What is your AFR at the exact same time the car is running "rough". If the trims are maxed out and/or the car isn't in feedback it will be forced to go overly lean and get a lumpy idle (that sounds cool) but really causes a lot of stalling issues etc. You may have to add a few micro seconds of deadtime.

 

Can anybody give me a tipp which injector scaling to use for
Precision 780 er with E85 ?

 

AFR's were around 14.3 with ECU trying to adjust now It seems to be running rich although the car idles smooth as silk (AFR way down to 12's). I am prolly out of the range of adjustment. I need to download MalibuJacks program and use it for logging trims as EvoScan seems a little odd.

Thanks for the reply by the way
