Engine re-mapping

had my Cherokee re-mapped about 3 weeks ago. 170 to 200bhp and torque up from 350 to 420. runs great and can feel the difference solo but not towed yet. should be ok though and help with mpg I hope. would not use one of the plug in one's as they just cheat the engine to think its cold so forces more fuel to engine. that's from a top jeep mechanic.

Had my CRV remapped last summer and really pleased with the result. I get about 50 miles more to a tank of diesel.  Pulling power really good. Wasn't cheap but I'm happy to pay that price.

From my supplier:

Yes we can do your honda crv it should have a bosh edc17 ecu which will be tricore protected. We quote around 30-35bhp and 70nm on average on those.  Price would be £180

mine was £299. did full diagnostics check on car first, then remap and another full check afterwards. very happy.

Is that the same "top jeep mechanic". that that told you your Cherokee had a CVT.

I’m interested in this issue and wonder -

1. Did you re-mappers tell your insurance companies and, if so, what was the response?
2. Have any of you experienced problems at MOT because your emissions have been altered?
3. Have any of you had problems claiming a repair under warranty due to the re-mapping?

Yes all three points would need answering for me to consider having a re-map. 

I had a PowerBox fitted to my new at the time '55 Kia Sorento, I also fitted  one to my new at the time 57' Toyota Hilux, I now have a Steinbauer unit fitted to my '14 Toyota Hilux and been very satisfied with all three vehicles compared to as they were originally.

Cheap is expensive if it's no good !!

Happy caravanning.

no that's me. to many abbreviation nowadays CTV and TC. mind I am M.E.N.T.A.L

Tinwheeler has asked some sound questions.

Another question on the Jeep remap, 

Was the auto gearbox reprogrammed to cope with the increased power and torque. 

The only way remapping can increase power and torque is to increase fueling/air volume. This might have a marginal increase in economy on a manual where the driver can make use of the torque by using a higher gear than an unmapped car but on an auto it that is not reprogrammed it must increase consumption especially when towing. It  may even accelerate wear and shorten the life of the auto box as gear changes will be now be at incorrect points on the the torque curve.
