Ecutek missing tables

Hi all,

I'm just compiling a series of tables for edit with my tuner through ecutek but can't seem to find any form of hotstart enrichment tables in proecu at all?

Basically car stalls after cranking on anything with 60+C IAT and have monitored a super lean start, pretty confident hotstart enrichment will cure me but tables don't appear to exist :/

Overrun enrichment doesnt exist also?

Also I'm looking at zeroing all tables in di ratio uptown and including 0.6 load, any one forecast issues with relation to this?

Thanks in advance!!

one way would be, took a "virgin" stock rom for that car (not from ecutek database) and star modifying what you dont have in ecutek, with romraider
then save, and reapply all other things in ecutek

slow and painful, otherwise you could ask a master tuner to take a look, they usually have access to more tables
anyway compare very well tunes on ecutek and romraider, hotstart could be some of the "cranking fuel" tables in ecutek there are a lot of them

Elso lots of ecutek users would have problem

Note some injector scalings are for 40 psi and car euns about 60 psi fufel pressure so that needs to be taken into account

Note car stsrts on port only then runs on port only for a minute or two regardless of whats in the pi\di tables

The maf correction after start tables provide some emrichment their in neutral and in gear tables.

thanks so much fellas for the comments

"star modifying what you dont have in ecutek, with romraider

yeah man I've been doing this and have a series of tables already sitting, waiting for pasting. cheers bud

Steve99, you make a good point that many ecutek users would have the issue. I may be attacking it incorrectly. Unfortunately I cant really alter injector scaling as itll impact fuelling for everything else, nor do I have the expertise to dictate values in that field as it doesn't seem my tuner does : /

does thew car still look at maf after start tables even post 80c coolant? cause it doesnt go through the warm up process like at 70c or under. maybe I can increase the values in 80c+ as a last resort part fix?

the DI ratio was more for cruise drivability, im really favouring DI more but worry 0.6load is too high for DI only on e85 3000rpm ish

Higher coolant temps have less maf offset in standard tables

Also have a look at
