TRD SC & CAI DONT WORK?

[DatSRBoi]

I was reading this one manuel and it say qoute

" Caution: do not use any aftermarket "cold air intake" kits with the TRD supercharger. The oe air filter hoursin and the or mass air flow sensor are cirtical for the correct air/fiel ratio calibration with the TRD supercharger. Etc Etc"

So now would that mean its better to keep ram air and not cold air? Could cold air really ruin the cars MAF sensor and throw the car off track and tune?

Makes me wonder if ram air nor cold air intake be safe with the supercharger.

no it cannot ruin the maf sensor, but bc of the intake volume change, there will be a change to the tune of the car, but the car is designed to compensate for the difference and handle it

Even thought i'm not boosted.. With the Injen SRI i was running more lean than with the stock air box with k&N or TRD filter.

This can be dangerous depending on your situation. I still have the Injen installed but i plan on taking it out sometime soon.

I really lost allot of Low end power with the Injen.
Running lean can be a bad and good thing depending on your set-up.

Yeah Im kind of reading up about that. Our sensors arnt the MAP sensors so MAF would throw the reading off on a bigger pipe intake aka aftermarket. I also notice the designs of our specific MAF sensor arnt really strong. Running boost must put allot of stress against the sensor.

Yup, Thats why some have gotten the CEL with just intakes. Some have been lucky. I've gotten the CEL light with my Injen once. I floored it on the freeway and the CEl came on. I got a reading and it was the MAF Malfunction. I just resetted the code and it never came back. But then again i haven't really floored or took my car to more then 4500 rpms at all recently.

But just to be on the safe side i'm putting my stock airbox back in with the standard TRD filter.

I never got a CEL with it on....


btw whats MAP and MAF stand for?

[jhenty]

this is a problem that can be solved with tuning, such as the apexi afc. The solara is not designed to compensate for this much difference in air.

Yeah true. But thats allot of money we're talking here even though yeah yeah money=power..Just saying so. But Im still thiking thats allot of stress on the small sensors.

MAP=Mass air pressure. This is what gives honda quick power without CEL
MAF=Mass air flow.... This is the one that doesnt like aftermarket parts with CEL

[jhenty]

your right dats, it may end up being expensive. Im not sure of a real solution, I dont know how hard tuning is to know if its something one could do theirself. What about the vortech FMU?

[Mandarinsolara]

lol
it stands for
Manifold Absolute Pressure, aint you ever heard of a honda

HKS VPC kit is the only way you can get something close to a MAP sensor on a toyota

[Wang2k]

lol mass air pressure

[Wang2k]

So hondas are speed density systems? That would actually hinder them wouldnt it because they are very sensitive to vacuum changes and such...It doesnt really measure the air coming into the engine it just knows the vacuum and percent of throttle opening, engine speed, etc and uses a program to figure out the amount of fuel the engine needs.

MAF knows how many grams of air are coming into the engine, along with the tps and rpms..this style can take a lumpier cam and sing with it because its not limited to a stock program..

Right or wrong?

[RedPhoenix]

you could get a engine management that rids the MAF. expensive, but the MAF is a pain in the ass. Im glad my 5sfe uses MAP, but I know my Greddy Ultimate has the ability to convert MAF to MAP with a new sensor. A lot of Supra guys are loving this.
