yes you have to trick the ect to read cold enough. its called "startup enrichment mode" when it gets to operating temp, then it shuts off the enrichment. this mode will only really help you when its colder out. like in the morning. other than that youll waste gas.

but the car will never get into closed loop mode. its not the way to make more power. its comparable to cutting your springs with a hacksaw to lower it.

you want to add more fuel to your 2nd gen 1.9? you go buy a cheap adjustable fuel pressure regulator for 87-93 ford 5.0 v8s and install it.

hook up a pressure gauge and tune it til it runs how you want.

Well, my guess would be cause nobody wrote one up and posted it! Maybe it's time somebody shows us how to waste more gas at the price it's at! LOL!

ok, if thats true, then how come my car has more power when its cold? I realize the intake and everything is cold, which helps, but surely it can't make that big a difference. I know im not smoking crack either, there is a difference. :D

I don't feel bad about burning a lil more gas. Untill soccer moms stop driving their two 8 year olds to practice 5 days a week in their gas gulping Hummer H2, I'll dream of my turbo :D . I don't know bout you, but I'm willing to bet that I'll go boosted before they trade the Hummer in.

Granted, I used to drive this V V V V V which got a fabulous 6 miles to the gallon in the winter. 8O

If all it took was more gas to make more power, every one would have 42lb injectors with a stock motor making 400hp and running 11's.

Your car feel's faster because it's cold. The air is more dense, the IAT sensor is reading colder so that's advancing your timing to add even more power.

Is there any way to get the car to run in cold start mode all the time? I notice with my car it has a ton more power when its in the cold start loop. Thanks. Josh
actually VW guys used to do a similar mod that would do this at WOT and it would give them a little extra power

trying to keep in it this mode all the time would be a bad idea though and would most likely cause other problems in the long run

Your car also feels faster on cold start because it'll idle way faster depending on how cold it gets out. Once it idles down as it warms up you still make about the same power.
