ls turbo?

[masonhenson]

ok guys please dont flame i am really trying to figure this whole turbo thing out.. i have an ls swapped 97 civic and i reaaaally wanna go boost.. i was thinking small turbo maybe 4-5 psi.. i need to know what i need to do about tuning.. ive heard people talk about a missing link? i dont know what that is so please inform me.. and also my car is obd2 swapped and the computer i think is a p06.. correct me if im wrong if anyone knows.. can anyone help me?

just go boost thats what im doing and ls turbo running it on 8 psi for daily getting it tuned on hondata s200 probably with a p06...as for tuning if your not sure message some sponsors or call the shop (topspeed, mainstream, lethal injection, batlground ect......) take their advice

I can provide you with an ECU for tuning. PM me for details.

The missing link is really outdated, so is an FMU. What youll want to do is get a complete turbo kit.

Check out the sticky at the top of this forum with all the details.

missing link makes it so that MAP sensor doesnt notice that the air in the intake mani. is on boost instead of vacuum, so that it wont throw a CEL when you actually hit boost.

Right?

Mason??? Turbo...i thought you going to buy some supercharger from your work? get rid of those fat five first then worry a F.I

Kinda

The factory ECU only reads up to 100Kpa absolute pressure or 14.7psia absolutepressure (dont worry ill explain)

The factory ecu is not configured to run POSITIVE Pressure (boost) so when you turbo your car and run a stock ECU the second you hit boost it will throw a CEL. Your ECU has TABLES and the tables correspond to atmospheric pressure (vacuum, load, etc) and RPM. Imagine a factory ECU reads from

0KPA to 100 KPA (Atmospheric)
(100KPA is 0 VACUUM, or WOT)

Now imagine a boosted car reads from 0KPA to 150 KPA(positive pressure)

When your ECU gets to the 100KPA spot , thats the end of its data stream. When you go past that, the ECU has NO REFERENCE for what needs to happen, so it wigs out, throws a CEL.

The missing link simply bleeds boost off BEFORE the map sensor so the ECU never sees it. The only problem with that is that your ECU still only sees to 100kpa when in fact it SHOULD be operating in the 100-150kpa tables. So drivability suffers, power suffers, etc.

When someone CHIPs an ecu, we load software that enables the ecu to see past the stock 100kpa reading, ie it can read boost.

If you get bored, look up Absolute Pressure vs Gauge Pressure

Look up Atmospheric Conditions

Look up KPa

^ Missing Link FTL, see scotty at mainstream, he'll hook u up with a ECU and a sweet tune

yup.

give me a call and i can answer any of your questions.

ill call you later today. im really just trying to figure out about how much the ecu and tuning would be

[masonhenson]

oh and i wanna keep ac

[Vteckidd]

You can keep AC no problem

Most hondas around here go to Mainstream to get tuned, IIRC they charge $140/hour. Most boosted cars are 2-3 hours.

[masonhenson]

called scotty just now.. very informative.. my phone crapped out tho.. ill call back later

[T34me]

good deal, now shrink your sig
