Turbo Help - Chip & Boost Setting

[Mikey16vClio]

I know there is a few with turbos who come on here plus some experts so thought i might give it try:

I currently run a T3 stage 2 at 10psi with a 195 Superchip and standard injectors. Piper cams, IK, S&S xorst.

Will the superchip which is off the self work fine with the T3s power deliverly as it would be programmed for the standard T2s deliverly or will the map sensor mean itll be fueling fine though-out the revs?

Plus i plan on running 15psi with 701 biege injectors, should i have a mapped chip?

Any info appriciated.

yeah bin the superchip and get something decent.

It will work and run but the T3 is a different animal entirely from the T2.

Also the superchip will be programmed for the T2 and the stock injectors. Another turbo and different injectors may make it run ok but the superchip as far as it will know is still running stock clobber so when it adjusts the fueling etc its doing it for a T2 and smaller injectors.

So yes a mapped chip is the way to go.

Most guys use a unichip - have you had it checked on a Rolling Road - FRSTs are 12 years old and most are running the wrong boost etc. I took mine to AVA who adjusted the fueling and timing to conicide with rasing the boost to 15psi. Its was running the wrong boost when i put it in.

If you know somewhere thats good with RSs take it along and let them check it all out to make sure- the last thing you need is trouble by running the car when its not set up correctly.

More sad facts from the brain of Chris!

The RST left ford producing 132bhp at 7.25 PSI of boost. Except they didnt.

Most never put out standard power due to weak actuators etc. A lot even when new only had about 110bhp.

Some were only boosting to 2/3 PSI

Mass production has many faults.

An RST running the factory power figure and in top nick is actually rather impressive.

chris beat me to it.........higher flow injectors and higher boost will requite totally diff maps, plus boost characteistics will be totally diff, changing ignition and fueling.

 

[Chris_H]

aye Ben only just beat you...only by about 2 hours or something! lol

 

[BenR]

hey man!!!!

im on holiday!!!!

 

[007]

Some were only boosting to 2/3 PSI

Its funny you say that Chris - I got rid of my first FRST as it wasnt as quick as id hoped - I got a second when prices plummeted - it was the same but I decided to mod it. The first thing I did was fit a boost gauge and it was only boosting 3 psi. I have to admit - for all its faults when running 15psi it was a lot of fun.

 

[Mikey16vClio]

Im not harming it in any way by running it as it is.

Shouldnt the map sensor be correcting the fueling as the revs increase?

Its a 195 chip which surposable is set to run 701 biege injectors however is fine with standards.

I wanna get a Bayjoo chip and 701 injectors and run 15+psi eventually. Ill get it set-up then but Ian @ Racetek (highly respected geezer) said itll run fine with-out being mapped.

Thanx for the help. Ive got better answers here than on fiestaturbo.com. Ha.

 

[BenR]

the map sensor doesnt do anything but provide the ECU with a signal that informs it of manifold pressure. Its the ECUs job to calculate or reference the fueling needed depending on throttle position and rpm.

So, ill run, just not very well.

 

[Mikey16vClio]

Manifold pressure meaning (inlet) boost pressure. Hence detecting when the T3 kicks in, hence fueling properly?

So u think to get it running sweet it needs to be mapped with a Bajoo chip?

Or just get a Bayjoo chip like Ian @ Racetek suggested?

Still have the problem of the T3s different power deliverly though.

Thanx

 

[Chris_H]

the MAP will sense the boost but the ecu will still be fueling for a T2 and the smaller injectors.

lets say at 3psi boost at 50 degrees throttle opening the pulsewidth is 0.8ms. Now 3 PS! at 50 deg throttle with a T3 and larger injectors at 0.8ms may make it run to rich or even too lean depending on the rpm.

 

[BenR]

dont matter weather its a bayjoo chip or a mohammed kahn chip or maccy D chip, it has to be set correctly..........if it aint, its not gonna run sweet, not just about detecting a boost increase.

 

[Mikey16vClio]

Arrr, but it should be alright? Ive standard injectors at the mo BTW.

So whyd u think an expert thinks i dont need it mapping just the Bayjoo chip? I dont think they do a specialist chip for T3 converted FRSTs BTW.

Basically u saying its ok to run it as it is but would be better for the best possible power deliverly to have it mapped?

Whats the difference to it being mapped and live mapped?

Cheers.

 

[BenR]

ok, first off, the bayjoo chip will essentially be a remap.......it will have changed parameters.

Why does this expert say so, well ask him, only he seems to have a reason......

All this off the shel mapping.......its only soo good, just like off the peg suits aint perfect.......get one tailor made.

mapped and live mapped, in this case, off the shelf and the other done as a result of checking how diff maps will affect it and keep on going till its as gooda s it can get or they get bored and charge you anyway! hahaha.

 

[Chris_H]

Expert.

Long have I wondered what this term actually means.

At one time I thought it was someone who knew a lot about a subject and was always striving to find an improvement and exhaust all the options to a certain area.

But in actual fact I have found that an expert is actually a muppet who thinks he knows everything and has such ignorance he is not willign to learn or accept he is mistaken and they are very lazy and dont want to develop things and they just want cash as fast as posible from whoever.

The car will run, it may even go pretty good but as Ben puts it it will not be running sweet.

A standard ecu in a standard engien is not goign to be very good either. every engine is different and thus needs different fueling, ignition timing and so on.

Comprimises are all very good but you shoudl really do things properly.

Ahmed Bayjoo chips are pretty good though I have to admit.

you have to get with these young persons slang...........its the only way to get through to them.

Those cam are whickkidy whickkidy whack!~ (bad)

damn these be smokin cans (a very nice muffler)

etc.........i provide tuition for the elders and 80s children, fees can be adj for boost.

peace out

"pure hardcore!"

"they call me crazy horse, cos Im mental and look like a horse..."

"pure dead brilliant"

Oh yes I know the slang! lol Ok I know the scottish slang (best in the world fanny bas ye dinnae like it Ill pish on yer trainers).

 

[BenR]

well thats me out of a job............

 

[007]

Chris you forgot the "nn-that" thats added to Scottish slang

"pure hardcore nn-that!"

"pure dead brilliant nn-that"

 

[Mikey16vClio]

I thought the £300 installation and setting-up charge included testing the car by setting up meters (xorst gas analyzers) and stuff then programming ur Bayjoo chip to the way ur engine worx (mapped).

Whereas live mapped meant u had it on a RRd to fine tune every aspect of revs vs fueling etc in the way BenR previously described.

Thanx 4 the replys peeps, keep them coming.

 

[BenR]

dont know how you simulate load with no RR.......lol

i dont know what mr.bayjoo does...........does he use a RR or an out teh cupboard chip?

 

[Mikey16vClio]

Im clueless, jus taking a stab in the dark.

Maybe mapped includes 1 run on the RRd and the readings used for mapping the chip whereas having it live mapped takes hours of fine tuning on the RRd.
