yes, but this makes the amount of correction done adjustable, so you can perfect it...

hmm i opened up a stock gsr map (p72) and the target lambda on low cam fuel just ends at 5000. from 5000 on in all vaccuum ranges, its just 0.00. is this normal? id think that this would throw off tuning, no? is this a problem/glitch/bug? or is the p72 code just like that?

CROME primarily supports the P30 bin. You can open a P72, but you wont always have all the options available.
If you look around on PGMFI.org, there is a P30 bin that has all the P72 tables and same MAP scalars.

I used the new version of Crome for the first time today and have to say it's a very clean and powerful program to tune with. I've been trying to tune a set of ITB's using Uberdata and it worked but was still not perfect. I tried ITBtools using Crome and it's much less "jerky" and with some more tuning I feel these things will run like stock. I wish it weren't pooring rain out right now just so I can go play with it some more.

i cant get datalogging to work . it says "bad response, check your settings" but my port settings are the same as the settings on crome. im using a serial connection. datalogging works perfect on uber, but wont connect on crome. whats the deal? and yes the rom on the chip i tried datalogging with crome was made with crome.

You need to cut the J12 jumper in your ECU

Go to pgmfi.org and read the wiki sectiond there is a step by step write up on datalogging w/crome . That is how i figured it out.

hmm, j12 huh? have a pic of where that is in the ecu?

also what does the remove checksum thing do?

Chris Harris

Look on your board, its in a different spot depending on what baord type you have. It's labeled "J12"

Removing the checksum does exactly that, removes the checksum.

gsrcrxsi

but what is the checksum? lol

and my board is a p28
