This was supposed to be a simple remapping session, NOT!

So in the last video we fixed the fuel pressure and over boosting issues on this mk7 fiesta st 180.
my plan now was to use HP tuners to remap the car to stage 1.
it wasn't easy and the fuel pressure problems returned when i added more boost so a long process of diagnosing and fixing it ensued
mods on the car so far
st200 airbox an filter
miltek sport race system

Steve I can imagine you don't make alot of money from this channel, but I just wanted to say your content is really appreciated. I learn alot through your videos, and it always makes for an interesting watch.

[@Sparkplugsteve]

Thank you.

[@robbiegriff725]

that's my favourite stretch of road for "data logging" 😁 followed by a quick "data log" up 'banog hill

[@Sparkplugsteve]

Yeh were very lucky here with that hill. Works the car hard to for the logs.

[@phillloyd6356]

Well done Steve. Our cars do "try" us many times, but you stuck too it

[@boastyy]

Great job Steve, car looks to be running great. Glad you managed to sort out the fueling issue, all good experience if not a little frustrating but you got there in the end. Well done mate.

Hi steve iv got my fiesta st in october iv learned so much about it since watching your videos great content keep it coming 👍

[@Sparkplugsteve]

Thank you Lewis

[@keithstapleton7805]

Good to see you helping others, but please look after yourself first with some liability insurance. I’ve seen too many times things get ugly when cars go wrong and owners forget the favours done for them. Sad, but true.

[@alex98uk]

Would be interesting to see it on the dyno and the figures it makes, if possible 👍🏻

[@MrEggyman99]

My car had major overboosting issues whilst doing test pulls with Pumaspeed, and after 3 days of having the car, trying countless different changes and runs they couldn't get it to stop. It was boosting at 17PSI with a Turbosmart 7PSI actutor on, and they were pulling their hair out, so in the end we put the stock actuator back on and the problem went away! Now it runs beautifully :) They said they've never ran into this issue before that couldn't be fixed, and they even took apart the actuator to see if it was actually a 17PSI one with the wrong packaging, but it was a 7PSI.

[@Sparkplugsteve]

The map obviously wasn't set for the actuator and because they can only flash map and not actually map there's nothing they can do to alter that themselves

[@IneptVirus]

Aftermarket actuators/bovs/shiny boost bits always cause issues in every car I've seen. Don't change what doesnt need changing

[@87sprintqf]

Hi Steve - i like your videos. So im familiar with doing flash tuning using taxtrix cable and openEcu. Ive never used HP tuners - what are the issues with flashing a Fiesta (Vinlocked etc?) could you do an episode covering more around using it? Also i note your not logging a wideband? how much headroom do the stock injectors have in them? more than the stock turbo can demand? cheers

[@hairycornflake8580]

Great vid Steve. So did you manage to override the Revo fuelling in the end?

[@Sparkplugsteve]

Yes all explained in the end 👏

[@markwalker1208]

I did a compression test and my results are very different. 150 on cylinders 1 & 4 but 125 on cylinders 2 & 3. Not sure if I've got a problem on the valve stem seals in the middle or got an issue with the pistons rings on those cylinders or there is a break in the head gasket in the middle. Got no carbon in the coolants tank as liquid stayed blue like yours. Any ideas?

[@Sparkplugsteve]

Pour a capful of oil in the low cylinders. If the results increases significantly it's the rings.if not it's something else.

[@fordyford]

Did you flash a stock file back onto it before uploading the new stage 1 remap? Again, although the Revo map seemed to have the issue on the car, it was about as mild as you can get on a 95 fuel map. Glad it got sorted. Will looked to enjoy himself lol.

[@Sparkplugsteve]

I did but the map I flashed wouldn't clear the old map completely. I have a selection of base maps so once I sussed out what was wrong I tried another one and got it fixed.

[@fordyford]

@@Sparkplugsteve yeah good stuff. I guess that is why Revo have their own base map they flash.

[@RevoHQ]

@@Sparkplugsteve The best solution is always to flash a full factory file onto the ECU first before applying any other tuning. Any Revo dealer or tuner with access to full factory files and the correct tooling would have been able to do this for you and would have possibly saved some time and frustration. The reason for this is mainly because we add in switchable mapping and additional data/tables onto the ECU which can't often be read or written over by some flashing tools which only access a limited part of the ECU structure. This might still be a helpful option for you, by putting the ECU fully back to stock, data logging, and then applying your software again. As a side note, it looks like this vehicle was running an older software version from 2016, and there have been various updates since this time.

[@Sparkplugsteve]

@Revo hi and thanks very much for taking the time to message. That's much appreciated and yes as you have guessed I'm just a hobbyist and this is a family member who I decided to help out. A pro tuner for sure would laugh at my struggles but it's a lesson learned and I appreciate your time.

[@RevoHQ]

@@Sparkplugsteve Every day is a school day, always something new to learn. You come across really well and do explain things clearly. With most calibrations, you would have been fine, but as above, we write and flash full ECU files built from the stock calibration. Therefore, some ECU’s we’ve encrypted, this is mainly down to the switchability functions of Revo software. This encryption only blocks the ECU from being read, preventing our software and tuning from being copied. However, a lot of the time this causes people to assume we have "locked" the ECU. However, a factory file can always be written to the ECU and new tuning applied. So always worth putting the ECU make to a factory first as you have a clean slate for logging and diagnostic work.

[@trfred4059]

@@Sparkplugsteve

[@dannbaker]

Was something in the tuning locked by Revo which stopped you from making changes? and that's why you had to start with a fresh base map?

[@Sparkplugsteve]

Yes exactly this.

[@dannbaker]

@@Sparkplugsteve what ever it was hidden didn't seem like it was right

[@RevoHQ]

Basically, it is down to the switchability of our mapping, where we add additional data/tables to the ECU so customers can use our SPS switch to change performance modes within the ECU via the OBD port. A lot of flashing tools don't have the ability to access these areas of the ECU or the function to flash a full factory/stock file back onto the ECU before applying any new calibrations. We would always advise visiting a Revo dealer or tuner with access to factory files to flash the vehicle back to a "full" stock before proceeding with new tuning :)
