how do i get the product key its been a while since ive done this?

[Matt]

If you have lost your product key. Email us with the original licence name/email address that we generated the key for to look it up

[bonomoskat]

i guess im talking to you in that email lol

Ok i fixed that rom pack problem ! got everything working now it has a error when i start saying "the file you have loaded was saved from an ecu synced image and synced images do not contain all ecu programs and file data " So im assuming i have to re sync the ecu with a base image and work from that and compare my current image . ? Do you have a base image that would be better for work off of?

[Matt]

Hit download button on what you have in the ECU and then post that up

[Matt]

starting point attached (1000CC/Z32 MAF)

[bonomoskat]

here it is downloaded from ecu

[Matt]

okay just upload my file for now and see if you have the same issue still

[Matt]

so I compared that tune file using the Nistune compare feature against the factory 53F01. The file looks completely different, like it is from a different vehicle

Explains why you are having issues using that 'tune'. Upload the file I posted here and try that to start from

[bonomoskat]

ok now ill just copy the timing map and the fuel map and see how it runs . Do i need to worry about all the other setting?

[bonomoskat]

so i started it with your tune and it runs super lean and once it drops to a idle it go super rich .then tries to die . i messed with the k value doesnt do much.

[bonomoskat]

If you can text me it would be much quicker ! 7575897574 thanks !

[Matt]

Sorry I cannot do that (not in the USA to start with)

There are a few things which can be checked:
1. Check if your AFRs are consistent with a certain K value from low - high low. If they are not then check your MAF. Where did it come from and it is a known working unit? Increase your K value to get a richer tune. At idle pull your latency lower

2. Watch your injector time vs your AFRs and log those

I assume you have read pete tuning guide to dialing in K constant?

Those injectors are quite large and will be difficult to dial in compared to say 750CC ones

yeah i just ordered a new maf it will be here saturday. When i uploaded the tune it runs good then when it goes to idle it drops fast then idles really rice but when up in the revs its running and matching numbers . So im thinking the maf is bad. No i have not but i messed with it a while ago learning from the guy that i bought the ecu from. i will read up on it though.
