Thanks!

 

I got hold of FIC 1450s added the data into the linearization table.

So how can i check if this table is really active and its taking effect ?

What other patches need to be added to the xml to make the car idle smoothly on these injectors

along with this table ?

spent a few hours working up on the idle but couldnt make it smooth, upon load it get very lean to around 17.

 

What data did you use? Did you get it from FIC?

There's no guarantee that any data provided to you will work perfectly. The values I determined from FIC data for my FIC2150s were not exactly right, and I spent several days of road tuning to come up with optimal values. Fine tuning injector behavior is a laborious process. And FIC1450s are somewhat inconsistent in their response, although your issue sounds more like a tuning deficiency.

For some reason this table will not show up on the 88590715 ROM, however, it does appear when I paste the code into the 88590015 ROM. Are the addresses different between these 2 ROMs? So far I have been able to utilize the codes given for 88590015 into 88590715. Any help is greatly appreciated and thanks for all your hard work.

 

Yes, it definitely works in a tephra ROM. If its not showing up, then there's something wrong with your ECUFlash xml file arrangement.

 

This is the data i got from a friend which is being used 5 evo 8s and 3 evo 7s with 1450 FIC.
i totally understand how intricate this process is. Uptill now what i have done to my evos i give credit to evo m community from which i have learnt. Not everyone on the forum has same set of skills as some of the pros here.

Those are the stock values.

 

Thanks Mr Fred.

Now do i need to email FIC for the 1450 injector data ?

i have 2 IPW table listings.

What i need to know that what is the function of each of these ? or they both are the same ?

1. Minimum IPW SHLL0

2. IPW Minimum
IPW minimum engine speed minum
IPW minimum low pulswidth correction.

 

You can try, but since they are no longer offering the FIC1450, I'm not sure that they will be able to provide any data.

Unfortunately, some of those tables are not appropriately named. I modified your list to make it easier to answer your question. Table 1 and Table 2a are supposed to do the same thing. I don't know why you have two, but both are not needed for FIC1450s. If you adjusted those, but it all back to stock. I have no idea what Table 2b is. No such table exists in the Evo ECU code. I suggest that you not alter it. Table 2c is of course the pulsewidth linearization table that you have been asking about, but since its not my table definition, and I can't see the whole thing, I don't know if its correctly defined.

 

ok ill delete these 2 definitions and stick with your linearization table.

There are a couple of things i noticed which i would like to ask.
During cruising at steady throttle the car jitters doesnt drive clean. As soon as the throttle is pressed jittering goes away and car drives clean. pulls clean all the way upto redline.

idle is set at 1100 its idling at 1000 and with a.c on it dips to 800. All this is related to injector scaling and latency ? or i am doing some thing right ?

which tabless can help me improve idle and cruise ? 9653 maf version
its becoming very frustrating now.

 

Which one of these ISCV tables can help me increase the idle and stabilize the AFR swing ? or do i need to add some other ISCV tables which actually control idle and start up fueling ?

 

You're asking questions that can't be answered without seeing logs and observing how changes to the tune affect the behavior of the car. You need to keep reading, learning, and experimenting with changes, or find someone who can tune your car. For the latter, just be aware that there are tons of people who claim to be tuners but are nearly as clueless as the next person.

 

ok
