Chipping FAQ

Mhh.
And if I well understand, to run E85 on my B204FT stock engine (and look for about 250whp and more torque), all I need is :
- your set of chips ;
- bigger injectors ;
And that's all ? LH2.4 will do the rest ?
Considering I never have to start the engine below 5~8 ?C.
Thanks a lot for your tips.

Yes, that is correct.

And on that engine I have a very good recommendation.

Listen to what I have to say (not just you AlizeE, but all of you who owns a car with a B204FT/GT):

The B204FT and B204GT can produce a lot of power due to the good efficiency, but mainly due to the type of engine management system it has. LH2.4 and EZK in all its glory, but that won't cut it when trying to get 250HP+ out of injectors that small.

The TCU and EGT sensor will make it possible. It will run quite lean at high boost, but it will see the exhaust gas temperature and adjust accordingly. After a while it will lower the boost and richen up a little bit if it is driven hard.

And the important thing, that is when running E85:

To run E85 you would normally use 42% bigger injectors. But in this case you should run 50-60% bigger injectors. The EGT sensor will then allow you to use higher boost and also keeping the boost longer (when driving it hard). Probably not lowering the boost at all, and not richening the mixture up. That would make the car more powerful and have a more consistent performance.

On a B230FT, the oversize in injectors would not really do the same thing. In that case it would just help you more when it comes to cold starts and acceleration enrichment (and of course the ability to run higher boost because of the access to more fuel).

Fred, could one add the b204FT EZK, ECU, TCU, EGT and your chips to a b234F +T and reap the same benefits?
Click to expand...
Yes, you can do that.

But you know... I already have chips for the B234F+T that are much better suited for a 2.3L engine and 2.3L 16v head (the engines are not the same and the burn rate and ignition advance would be somewhat different, even though it would probably work pretty good).

Take a look at that section of my FAQ post.

what about these ecus fred , am i right they use a 60-2 flywheel sensor ? is it the same for the NA B230E ?

oh , heres teh link

I have no idea about the flywheel actually...

When did they start using 60-2 anyway?

Since that is for a carbed version with a different head and different cam, I doubt that it can be used for the B230E which was too different from the B230K.

The B230E had an EZ118K ending in 009 instead of 007 like the B230K had.
 
How do you raise the boost with the stock solenoid still there? I removed mine... I think it was broken, it didn't work... Also Fred, do you have the part# for the sensor in radiator?

Click to expand...
To raise the boost with the stock solenoid still there you need to trick the TCU. Put an MBC on the line to the TCU. If you need to increase the boost even further, then put an MBC on the line from the solenoid to the turbo as well.

I do not have the number for that sensor available right now unfortunately.
 
Fred, which injector fits better (LH2.4, 012AMM, E85, your Chips):

http://www.racetronix.com/17113841FM.html
2Ohm, Peak-hold ECM driver modifications required, the original FT inj. are also 2Ohm, so would this fit? Cone Spray Angle - 20.3 degrees - single spray cone. Approximate cone angle for 90% of spray volume.

or

http://www.racetronix.com/3172FM.html
12Ohm, this high-impedance injector will work with all factory ECM/PCM injector drivers (with brigged resistors), Spray Pattern: Pencil

Is there any significant difference (especially the Spray pattern) between those two injector types, pros and cons ....?

The Siemens DEKA injectors (the last link) are better in every single way. At least for LH2.4.

Better spray pattern and atomisation. They also react pretty good and have very good low flow capabilities.

I run these at the moment: http://www.racetronix.com/L107FM.html

And I ran these before: http://www.racetronix.com/3145FM.html

And will swap those back in again, since I used the ones above them when I drove in places where it was hard to get E85 and I had to mix with petrol.

I have tried greentops, CFI's (two different sizes), Bosch motorsport injectors, Delphi and now the Siemens. The Siemens injectors are definitely the best ones I have tried, both sizes. And I don't think the smaller Siemens injectors are any different.
 
Thanks a lot for the past replies ! Anotehr questions :
- Is your B204FT still smooth to drive with your set of chips and E85 ? I'll get my new 960 turbo in a few days, I don't want it to much brutal, but just more powerful in medium and high revs.
- So these injectors ( http://www.racetronix.com/L107FM.html ) are good for my project (B204FT, chipped, 100% e85 and stock exhaust - will add race cat later), and are they 'plug in' like stock ones ?
Your knowledge is great, thanks again, and sorry for my bad english. :)

No, those are not the same.

I will add the explanation to all the components in my FAQ soon so please hold on until then and it will be done right.

And if it is the Immobilizer ver. 2 then it will not have a separate box (the Immobilizer should be integrated in the ECU).

Hi Fred,
It was the explanation to the components and the immobiliser details I was wondering about.
I am not in a huge hurry and no-one is paying you for your good work so it is just a question from someone who knows much less than you.

These will work better since you will use the AMM you have now: http://www.racetronix.com/3172FM.html

And the smoothness is much better on the chips. And most definitely better when E85 is used with that. The chips and E85 is what makes the engine smooth. It is very rough in comparison when it is stock.

And with the chips it will be A LOT more powerful. Then add the injectors and E85 and you will have yourself a ****load of power.

When you are going to do some work on your exhaust, replace it with a sport system. The stock system is very restrictive, even for a stock car with 190HP.
 
Thanks for the link. I'll consider it when I'll have the car in my garage. It's great if the engine run smoother, I want to drive it daily in low revs without notice it has been tuned...

I think I have to use the chips with benzine (regular SP98) a few days (400 km ?), like you explain in this FAQ before empty the tank, replace the injectors and refuel with pure E85 before start up ?
With stock exhaust, can I expect 35 m.kg and ~ 250 whp ? Only the cat will be replaced, authorities aren't very friendly with noisy exhausts here in France...

'will order a set of your chips in a couple of weeks. :)

You know, it is the tune that makes it work like it should and perform at its maximum. Stock ignition maps are too retarded.

Get a 2.5" performance exhaust. Your engine will thank you for it. It will not be loud and noone will say anything about it, not even in France.

And I can't promise you any performance numbers with the stock exhaust. It will be a lot more, but how much I do not know.
 
just a few days i installed a JT 3" system on a 940. 2 straight through silencers and a 3" racecat. sounds good, not loud when idling and normal driving, didn't test it with more throttle. and i had a testdrive in a 940 with a 2,5" Simons system and that car was really quiet as well.
