[SFX] ECU Diagnostic and Tuning Services

[foxdie]

Hi all,

This thread is just a formalisation and feedback thread of the ECU flashing services I offer.

Services offered in the West Midlands area;

• Reading and clearing of EFI (Engine) / ABS / AYC ECU fault codes
• Live logging of the above ECUs and Innovate Wideband o2 sensors (if fitted)
• Live Air / Fuel ratio readings, diagnose faulty o2 / lambda sensors
• Log analysis services and a copy of the logs emailed
• Tuning / Reflashing services for all VR-4 ECUs (7201, H8/539, 7202 and 7203)
• Tuning / Reflashing services for Galant N/A V6 ECUs
• Tuning / Reflashing services for FTO V6 GPX ECUs
• Tuning / Reflashing services for all VR-4 autobox ECUs for faster shifts

Rates are as follows;

• £80 for the first hour (minimum of 1 hour)
• £10 per 15 minutes thereafter (billed in 15 minute blocks)
• Travel expenses are billed at £1/mile
• Additional £5 charge if you want either of Kens ROMs flashing;
  
  1. Version 1.03 which adds CEL-on-knock, larger fuelling / ignition timing maps, launch control, anti-lag and no-lift-to-shift
  2. Version 2.0 which adds CEL-on-knock, switchable maps (of which launch control / anti-lag / valet mode etc can be implemented)

The £5 charge for Kens ROMs is to support him in his development of adding new features. Please note that Kens ROMs do not work on early pre-facelift 7201 ECUs (metal case variety). All black plastic (H8/539 / 7202 / 7203) support these mods.

Please note the following:

• This is an evenings-and-weekends service only and my day job comes first
• It is your responsibility to make sure your car is ready to be tuned ie. no misfiring etc - you will still be charged (but with a 50% discount) if your car is unfit for tuning
• I take no responsibility if something goes bang (or worse) from reflashing / remapping an ECU
• Remaps provided will aim towards the safe / conservative side, I will not push it to the limit
• Backups of the ECU will be taken and made available on Dropbox in case of it needing to be restored later
• Anyone requiring a reflash / remapping will be required to confirm they understand all of the above before I do any work

What gains do you expect from reflashing N\A V6 Galants.

What gains do you expect from reflashing N\A V6 Galants.

A reflash on a Normally Aspirated engine is only as good as the mods that support it, a simple remap with no mods would probably only gain a couple of HP, but add a de-cat and a performance panel filter into that and you could probably make another 8-10.

The problem is that N/A V6's have a SOHC head which is rather restrictive (ultimately this helps economy though), I think that with a pair of DOHC heads from a VR-4 engine, a remap and supporting intake / exhaust mods that you could get quite close to 190-200 HP out of them.

hmmm .

[foxdie]

MMCFlash has arrived, so hopefully 7201 and H8/539 reflashes can now be done, I've got a H8/539 but I need to find a 7201 to test on though, any volunteers?

[alan]

i think soon you can prob have mine

[exevoowner]

I maybe requiring your services soon aswel lol

[foxdie]

Here to help when you guys need me

Just be "done" by Jason. One word: Excellent. Turns out I had a 7202 all along, so I'm mapped and now pushing 20psi with no fuel cut and lairy launches with anti-lag.

Thanks Foxdie!

[foxdie]

Nick, you are more than welcome, glad to help out a fellow member. Lemme know how the economy is now as well as the performance.

Pm me your email and I'll send you backups of your old and new ROMs

Need to update your sig now too

Wait, pushing 20 psi? I thought our turbos started surging at 16ish?

Hi Dan, here are some metrics;

jesus-ninja-metrics.png

Nicks boost gauge peaks at 20 PSI when floored, so there's a tiny amount of surge there, it held a stable 18~19 PSI (1.3 bar) through most of a 3rd gear pull, tailing off to the end as expected. The load peaked briefly at 210 which is loosely around 19 PSI so that confirms the gauge is quite accurate.

First thing you may notice is the knock around 3500 RPM, with a maximum count of 5 I'd have marginal concern over this and want to map it out (we did add more fuelling just to be safe) however given the following factors I wasn't worried about it;

• We were mapping on Tesco 99 fuel and Nick (Jesus-Ninja) confirmed that he normally runs it on Shell V-Power (better additives)
• Nicks boost controller (a TurboSmart e-boost mk1) has 3 boost presets, that last pull was on the highest of the 3 profiles and Nick confirmed he rarely uses that
• Nick has also fitted his car with an aftermarket knock monitoring system, we knew that was working perfectly but during the runs it didn't flag up any knock warnings
• Nicks pretty clued up and knows how to control his right foot if excessive knock is detected and to dial back the boost a couple of PSI

The result, according to EvoScan's estimations after entering the correct settings for a manual Legnum with passenger weight, was a tasty 257 AWHP and 316 Foot Pounds of torque (or for you guys across the globe, 192 KW and 428 NM), which after a very loose estimation of 22.5% transmission loss, comes out at 315 HP / 235 KW at the fly

Naturally all those figures are to be taken with a pinch of salt and the true test would be to stick it on Bens Dyno, that'll happen one day and Nick can confirm if EvoScan was on the ball

Quick question - how suited is the stock ECU, now that we can control fueling and advance, to control a bigger turbo and injector set up?

It's not something I've done personally but there is the option to change injector scaling in most ROMs these days. Given that a). I've been told that scaling works fine by 2 fellow tuners here on CVR4 and b). Evos using the same ECU chips as our cars have been tuned to well over 600 HP at the wheels with larger injectors, I'd say it's goer

[foxdie]

Added AFR reading service too

(For the uned. this means I can remap based on what your car is actually fuelling, also means I can diagnose faulty stock narrowband o2 sensors, if your car is using excessive amounts of fuel when driving sensibly this could be the case)

[Jesus-Ninja]

Cool - you have a wideband sensor that you can stick up the tail?

Yep!

Splendid. I may just have to come for a remap (again) once it's back together When we did my AFRs it was all done off the gauge!

Yep, happy to help you out when you need me Nick
