Flashing Coil Glow Plug light

[will21]

Hi all,

DTUK recently installed a tuning box to my car. Fantastic improvement to power and mpg. However, on two occasion I rev upto 4k and I lost power, coil glow plug light came on. Felt like my turbo went.

When i turned the ignition off and back on, it was back to normal. Continued my journey fine. This happened again today, when i went up to 4k rev.

Does this mean after the CR tuning box install I need to upgrade my glow plugs? or is there something wrong with the box causing the engine to trip?

DTUK is closed over the weekend but want some suggestions before I call them up next week.

Thanks
Will

Sounds like limp mode to me - because no matter how good tuning boxes claim to be they are never as good as a remap.

Sounds like the limp mode as stated above, the next solution I would advise is to buy premium diesel, drive the car at a constant rate in 4th or 5th gear for a while in motorway about 15mins at over 2000 rpm to burn of all the buildup in your car this should fix the problem. This is caused mostly by driving in town for short period of time, not letting the car heat up and burn those buildup good luck

Change the setting son your DTUK box. See what your running eg 4-2 or 4-3 and bring it back a notch. So if your running 4-3 put it to 4-2.

And you're still considering getting a tuning box?

What a mug!

I figured it out when I was out doing a run before.. unplugged the box and rev up to 4000rpm,, no engine light. So figured must be the settings on the box. had it on 3-2. Advised it was the best map.
Changed it to 4-3. Which solved it. Feels I dont get as much power on low revs but still running really quick. Sorted!!

Just to clarify-the box is now giving me atleast 225bhp 430 torque (before 170bhp 258 torque) and 68mpg!! (Before 45mpg) nothing more I can ask for really. Happy with that!

It's never giving you that power in a million years.

stage 1 revo is around 200 isnt it??

208.

Gonna stop selling it next week though and get some of these tuning boxes in before I'm out of a job

Tuning boxes are the way forwards, you can change it for different cars so it must be good. They have separate maps for each car, so that proves that theyre not generic

 

[olitaylor07]

You cant change them for each car. You can change the settings and different HP and torque maps lol.

 

[James_R]

I don't know why maps keep getting mentioned. It's a box with resistors in or a processor that limits voltage back to the ecu, manipulating sensor signals so the ecu cranks up boost and fuel pressure. No real calibration it's just guess work based on the assumption that the ecu will automatically compensate for the signals yet limit any that will cause a potential issue, like the above by dropping it into limp mode.

There's no map programmes, just slight perimeter alterations that adjust the amount of resistance per circuit.

And the figures are all bollocks.

Cr diesels all work on the same principal. They all have a high pressure fuel sensor, an engine temp sensor, a map sensor and electronically controlled injectors.

All the will be altered from car to car is the amount of resistance required by each circuit.

The box directly manipulates the signals the ecu sees I order to trick it. Altering these signals means it can dump more fuel in and or crank the boost pressure up.

Apparently you can according to the other thread thats going on about them>

The only real difference is the resistance values and the loom connectors.

Personally I'll have it remapped, but I really don't want to have to pay again to change it if I don't like it or if am selling the car, I just want something I can plug an remove when I want, and even take with me to another car, besides with many remap so see, although the get good results the still smoke like a chimney and I hate smoky cars, that's why am looking at this company because the claim the have solved with with a tuning box plus their review looks ok, you know the taboo that people with try something new cuz the want things to stay the same, I wanna try something new, ave always wanted a remap, but the smoking had put me off until now that this company claims no more smoke and you get results, so it someone who had this companies tuning box could comment that would be great thanks

^^^^

thats what this genius reckons

I dunno how tuning boxes work, as I have no interest in them

 

[James_R]

Some people are deluded.

Some cars smoke post map, yes. This is because who ever created the file has either not matched the AFR or has whacked loads of fuel and or boost in there to make it feel as fast as possible, usually on an older tdi or pd engine.

He's basing his knowledge on the problems of the past on different vehicles to his own.

The chaps on about a box for his cr170. His car has a DPF. This component will capture, catalyse and burn any soot that is produced from the combustion process, if it smokes after a map he has much bigger problems.

And he's pretty much saying people have maps because everyone else has them when the facts are quite clear that people choose a map over a box because they are much more refined, efficient and produce the best results, smoke free.

I know this but got the purpose of people that don't with the DTUK you get a booklet showing how to fit ect and you get 4 RR's printed out showing the difference in the 4 different "maps"

Map one increases the torque but keeps the HP the same.

Map 2 increases both

Map 3 raises where the peak HP is

Map 4 does both again.

(I think can't remember exactly)

I aren't starting one of the thousands of thread we have on here about remaps and box's.

I tried the box and sold it at the same price. I wasn't a fan and when funds allow I will be getting a REVO remap.

 

[James_R]

How was it adjusted? Via a dial on the box itself?

 

[kazand]

So your box is giving you a 30% increase in power, a 67% increase in torque, and a 50% decrease in fuel consumption. That's fantastic!!! What great news. For you, and whoever you need to buy your latest clutch from..... And your insurance.....
you have told them ...... Haven't you ??
