Ok My car is EWG as are all M235i All EWG cars have the upgrade turbo housing also ... its larger !! This is why there are dP's out there that dont fit for everybody's reference.

AS for JB4 v Race Ultimate there are several things to take into consideration ..... personally the JB4 didnt work well for me as I had some really crazy throttle related issues , but it works awesome for most people !! There is no doubts the JB4 is very powerful and supports very nice features, in fact i just purchased the EWG specific board to test.

But for ease of install and with stage 2 JB4 results or better the Racechip is a real winner for me its that simple.

All the best

Is anyone running a racechip ultimate with a EWG controlled car? I wondered if the ewg would still manage to hit the published figures.

My cars currently standard and I run 99 RON fuel (equivalent to 94 US?), can I increase the settings over what the racechip comes setup as or is this only for cars with sports cats/decats and uprated intercoolers?

Finally I notice people mentioning they haven't had any codes show up while increasing their settings and also data log, are you's using something like dash command and an OBD2 dongle to do this?


I'm currently stuck between the racechip ultimate and a stage 2 jb4. I'm put off with the potential hassle of having to remove/refit all the jb4 connections for dealer visits if ever needed where as the racechip is much simpler in that regard. However the built in fail safes and custom map 6 appeal to me with the jb4.

I'm nevering going to use meth and I may eventually upgrade to a 200cel sports cat.

Cheers

The EWG cars have better performance due to the larger turbo exhaust housing .... so when tuned you get faster spool better top end ability to hold boost in the upper rev range and it will support better performance gains overall !!

Just waiting to hear back from RaceChip (been in discussion with them today) but it's always good to get peoples reviews and thoughts that are currently using the product.

Fingers crossed the ewg cars aren't held back performance wise

I'm forgetting I'm in the 2 series forum, I have a m135i and noticed you do to hence my ewg question

I know the jb4 guys need to run the ewg add on harness to hit the higher boost targets as without it you can only get a few psi above standard, hence why I wondered if the RaceChip would be held back by it also.

However all seems good

If you worry for dealer visits as me (noob here so I needed the easy install) RaceChip, and let me start by saying every engine has different variables and depending where you live and your octane.

I have tested my RC from C up to 4 (1 by 1) 30-50 miles on each setting , no errors or codes. Each setting has a different behavior with fuel consumption and power ratio. For me C/D/E/F were improvement from stock car and still better MPG. Once I enter 0,1,2,3,4 territory Fuel Consumption increased but the power was X3 28i matching X3 35i 0-60 side by side. Remember the higher the setting the more fuel is going to use but also more power. Go 1 by 1 testing, for M235 as chaddy wrote F is the safest max for long-term. But every engine has different tolerance so take it easy

I have OBD2 Link Tool with Dash Command and also Torque Pro
For datalogging, temp reading, engine torque/hp and wheel hp/tq but you must have your cars setting entered 100% accurate.

Will the computer pick up and store any tuner detection codes from the use of the Racechip, or is it basically undetectable once removed? Wouldn't be surprised if the car kept a log of recent engine running conditions for diagnostic purposes that may look suspicious. Nonetheless, it sounds like a VERY tempting purchase given what people are reporting.

[chaddy74]

What build date is your car mate ?

I'd like to know the long term reliability of the RaceChip.... it only uses the same 2 connectors the JB stage 1 uses... so it can only control those 2 sensors...

It allows you to increase/decrease perf through the knob, but how safe is it?
specially when you can't control the EWG like the JB4...

the JB stage 1 is limited to 13psi i think for that reason, so you don't blow up your engine... I'm sure they could pump it up if the wanted and felt safe doing so but they don't
JB4 with EWG i believe allows higher boost cause it can control more things

I don't want to downplay the RC numbers, just wondering if that's getting achieved in a "safe" way....

I don't think the ECU will store any data from the RaceChip man.

pikcachu , I hear you, you have good point. I really hope that the RaceChip keeps on being reliable, this is one of the reasons I'll keep on testing the default settings for a while more. In addition, I will actually go to the dyno with the default settings when I have the time (when off from work).

Thanks for your contribution with this concern that I think needs to be taken into consideration.

Do any of you know how much boost is the RC hitting?

like from some aftermarket OBD2 gauge or app

[chaddy74]

You are actually incorrect !! You cannot just pump anymore boost into and ewg car without controlling the wastegate if you want too ! So 14psi is Max which is roughly 3-4 psi over stock !! Power isnt only about boost its about airflow and timing.

You think controlling the WG on and EWG car and cramming more boost in is safe long term ? I beg to differ.

Mate its all in the algorithms of a tune , I actually like what the Germans have done with there two sensor tunes , its superior in drivability in all the testing I have done to date ..... so lets just leave it there !!

But I have tested all functions on the JB 4 and if i didnt have stupid throttle issues I would have stuck with that solution, but I guess my car likes german tuners for some reason.

I will try see this info on my ScanGauge II this weekend and let you know.

[chaddy74]

Already have man 14psi !

This is my understanding...

Stock - 9psi
JB Stage 1 - 12.5psi (+3.5)
Scorcher - 13.5 (+4.5)
Racechip - you said 14psi (+5)
JB4 map 1: 12.5 psi (+3.5)
JB4 map 2: 14 psi (+5) (requires downpipe 93 oct)
JB4 map 7: 16 psi (+7) (requires race gas 100 oct)

for anything above 12.5psi 93 oct is recommended

I'm not saying that controlling the WG on and EWG car and cramming more boost in is safe long term.....

I'm just saying that 14psi with only 2 sensors might not be any safer...
Can control timing without CAN access ?

[chaddy74]

I Agree with you 100% on the safety bit for sure !! I will be the first to Cry and tell the world should I cook the goose.

I have run the manhart tune daily at 13.5psi for 7 months ... never babied it and I have never had one issue or concern or code for that matter.

Its my understand that Can access is for reading signals only not manipulating them.... ??

I will also say with Map 6 on the JB 4 I have seen 20psi and 18.5PSI at 5500rpm but I thought I was going to break something. Gearbox

I'm just saying that 14psi with only 2 sensors might not be any safer...

I opened my OBDLINK Scan Tool app called OBDLINk from Android market on setting F yesterday. Here's the picture attached

The 2 Trip Stats are showing Dash Command
- First one is RC on setting 4 showing 312hp/355tq
I guess I didn't stomp it as hard ^^^
- Second one is RC on setting F showing 321/399tq

But both show 21psi there

These are just an estimate and I'm still not done with the advance settings of the X3.

The 2 Diagnostics pics the car was cold started on Monday morning on setting F (snow day 16F) 14.5 PSI barometer and Intake MAP 13.92psi

[/QUOTE]

What I mean is that given that it has no CAN access, I don't know how it does to adjust any sensor accordingly if it can't measure any readings....

Also the fact that you can take the box out, switch some wires and put it in complete different car doesn't inspire me much confidence either...
meaning it's a "one fits all" kind of product instead of something designed for a specific engine

I guess time will tell

Do you have a trip stat for stock with no tune?
Also wonder how reliable any of that info is if it shows 21psi of boost
