The original daewootech forum

I'm also using water/methanol kit on my lacetti. And my purpose is lowering EGT. My pump is a custom modified Coolingmist. Remove pressure regulating circuit and attached some tubing and spped controller for adjusting pumping pressure without pump motor stop. And it makes to adjust pumping pressure ...

this is so awesome, i have a aveo (kalos) with a 1.6L, you my friend give me hope. how come you desided to use automatic transmission over a manual? what exacly did you do to the stock auto to make it stronger? It was done by a A/T tuner in Korea. I don't know exact work but just know that they hav...

It is a product of Maintech who is one of exaust parts maker in Korea.
And the quality is the best. ^^

Today, I fixed AFR competely. It keeps AFR 11~12:1 at full boosting 1.3~1.5bar. The problem was MAP sensor atmospheric pressure value. ECU judges atmospheric pressure value when key on before starting the engine. And controls AFR with MAP sensor voltage & O2 sensor value. In case of stock MAP sensor...

My lacetti is 2003 initial model and it uses Siemens Sirius-D4 ECU. And it tries to keep 14.7:1 when closed-loop condition relies on O2 sensor, but when open-loop(under full trrottle or some conditions), it will inject fuel in accordance with pre-set fuel map. And ECU remapping is adjusting pre-set ...

I have changed map sensor (to 2.5bar sensor) and adjusting AFR with S-AFC. However... it is difficult to catch it. Anyway, I checked dyno numbers again. AFR was dancing.... http://www.clublacetti.com/zbxe/files/attach/images/149/879/022/009/68733e28ad7e34923e55a6f52d53cc25.jpg Max Boost = 1.5bar(21....

I really like what you did with the car. I think it looks great on the outside and that extra power I know is alot more fun. What rims are those and what sizes? I hope the auto transmission holds up for you! Thanks exist3nce... Today, it is snow in Seoul... everything is covered with white.... The ...

Well depends i would like to be sitting in the car and control the boost but if its more then 400$ well going under the hood will have to do I'm using in-seat manual boost controller. And it is just USD10 in ebay... Simple and convenient, try it. And, as far as I know, needle valve or shut-off valv...

are they metal gaskets? i tought the factory ones were not! Hmm... Lacetti's genuine head gasket is surely metal, 0.75T, and I can check it in Service manual. All turbo lacetti(1.5L, 1.6L engine) in Korea use just stock gasket, 2 or 3 sheets. Ah, just one is using custom metal gasket. He is an engi...

Thicker headgasket?

I checked my calculation was wrong.
The correct compression ratio is 8.34:1.
And I used 3 gaskets together. GM genuine head gasket(metal) 0.75mm X 3 sheets.
Stock compression ratio 9.5:1. (1 gasket).

I fixed my thread.
