I only know this

and

from deerhunter2005. You can use both tools to level up faster.
But since EA implemented the new pursuit system three weeks ago, you only get ~850 money for one pursuit with this two trainers (in combination) with a level 50 account. Furthermore you have to complete a pursuit in at least 3 minutes, otherwise you won't get a reward card.
I'm also looking for a way to get more money in a short time. If you would use speedhack with CheatEngine to accelerate the pursuit to 3 minutes, the system would notice this and you get minus money. Anyway, if you would you speedhack, the cooldown counter would also gets faster and so you never could reach the 3 minutes.
So, all in all, I don't know currently how to increase money to an acceptable value (for me). Approximately 850 cash for one pursuit isn't worth to use this two trainers, because it's a waste of time until you someday have few millions cash. Of course you can let the trainers run overnight, but that would take (if you start with $ 0) about 98 hours (with a level 50(!) account) until you reach the maximum of money of $ 9,999,999. If you don't care about your electricity bill, you can try this but for me that's not an alternative to turned on my computer 4 days long^^
